This function is an internal API and belongs in v4l2-common.h, not
videodev.h. The return pointer and probe argument should be const as well.

79c6ff93c7 V4L/DVB: V4L2: add a generic function to find the nearest discrete format to the required one
Many video drivers implement a fixed set of frame formats and thus face a task
of finding the best match for a user-requested format. Implementing this in a
generic function has also an advantage, that different drivers with similar
supported format sets will select the same format for the user, which improves
consistency across drivers.

0e0809a588 V4L/DVB: videobuf: add queue argument to videobuf_waiton()
videobuf_waiton() must unlock and relock ext_lock if it has to wait.
For that to happen it needs the videobuf_queue pointer.

Don't attempt to unlock/relock q->ext_lock unless it was locked in the
first place.

vb->state has to be protected by a spinlock to be safe.

This patch is based on code from Mauro Carvalho Chehab <mchehab@redhat.com>.

9739768788 V4L/DVB: videobuf: prepare to make locking optional in videobuf
Currently videobuf uses the vb_lock mutex to lock its data structures.
But this locking will (optionally) move into the v4l2 core, which means
that in that case vb_lock shouldn't be used since the external lock is already
held.

Prepare for this by adding a pointer to such an external mutex and
don't lock if that pointer is set.

ee6869afc9 V4L/DVB: v4l2: add core serialization lock
Drivers can optionally set a pointer to a mutex in struct video_device.
The core will use that to lock before calling open, read, write, unlocked_ioctl,
poll, mmap or release.

Updated the documentation as well and ensure that v4l2-event knows about the
lock: it will unlock it before doing a blocking wait on an event and relock it
afterwards.

Ensure that the 'video_is_registered' check is done when the lock is held:
a typical disconnect will take the lock as well before unregistering the
device nodes, so to prevent race conditions the video_is_registered check
should also be done with the lock held.

96322b80e2 V4L/DVB: Deprecate stradis driver
The driver author seems to not worked on this driver since its conversion
from 2.2 to 2.4. Nobody is known to have a stradis hardware for testing. As
it still uses V4L1 API, BKL and probably some other old stuff, someone would
need to work on it to preserve the driver. Instead of investing time and
efforts to keep porting it to work with new API's, it seems better to just
drop the driver.

So, let's move it to drivers/staging and label it to die at 2.6.38, if nobody
cares enough to port parallel port support to gspca or to create a new driver
that uses the same gspca-cpia sub-driver.

cpia driver were re-written inside gspca driver, for USB devices. The only
functionality that were not migrated is the support for parallel port,
as:
	1) the developer didn't find any hardware;
	2) it doesn't  seem important to keep support for a parallel port webcam,
	   as this is an obsolete technology;
	3) the changes at gspca for it to work with parallel port would be very large;
	4) this driver still uses BKL.

So, let's move it to drivers/staging and label it to die at 2.6.38, if nobody
cares enough to port parallel port support to gspca or to create a new driver
that uses the same gspca-cpia sub-driver.

eaf2bcc923 V4L/DVB: imon: split mouse events to a separate input dev
This is a stab at separating the mouse (and front panel/knob) events
out to a separate input device. This is necessary in preparation for
the next patch which makes the rc-core input dev opaque to rc
drivers.

I can't verify the correctness of the patch beyond the fact that it
compiles without warnings. The driver has resisted most of my
attempts at understanding it properly...for example, the double calls
to le64_to_cpu() and be64_to_cpu() which are applied in
imon_incoming_packet() and imon_panel_key_lookup() would amount
to a bswab64() call, irregardless of the cpu endianness, and I think
the code wouldn't have worked on a big-endian machine...

- Minor alterations to apply with minimal core IR changes
- Use timer for imon keys too, since its entirely possible for the
  receiver to miss release codes (either by way of another key being
  pressed while the first is held or by the remote pointing away from
  the recevier when the key is release. yes, I know, its ugly).
- Bump driver version number, since this is a fairly significant change
  (for the much much better).

ee08940531 V4L/DVB: IR: export ir_keyup so imon driver can use it directly
The imon driver currently reimplements its own version of ir_keyup
(along with key release timer functionality also already present in the
core IR code). A follow-up imon patch will make use of ir_keyup and the
IR stack's key release code.

Trivial extraction from David Härdeman's pending rc-core merge and
device interface abstraction patchset to facilitate merging a patch
based on his imon input dev split patch ahead of the larger churn, which
is slated for post-2.6.37-rc1 (after Dmitry's large keycode patches are
merged in mainline).

44243fc2ef V4L/DVB: Remove the usage of I2C_HW_B_CX2388x on ir-kbd-i2c.c
Move the cx88 specific initialization for Hauppauge XVR remotes
into cx88-input, removing the need for test it inside ir-kbd-i2c.

The reference at cx88 for this symbol, at:

drivers/media/video/cx88/cx88-i2c.c:    core->i2c_adap.id = I2C_HW_B_CX2388x;
drivers/media/video/cx88/cx88-vp3054-i2c.c:     vp3054_i2c->adap.id = I2C_HW_B_CX2388x;

Can't be removed yet, since lirc-i2c still uses it.

8403472f19 V4L/DVB: usbvision: remove BKL from usbvision
Removed the BKL from usbvision.

There was an initialization bug as well where the i2c bus was registered twice.

Although when the BKL was present no oops was generated, I did run into
other i2c problems. Now that I protect against duplicate i2c registration
that bug is now gone as well.

But trying to disconnect the USB cable while someone is still using the device
still leads to a crash.

226c0eeaea V4L/DVB: videotext: remove this obsolete API
Remove the vtx (aka videotext aka teletext) API from the v4l2 core.
This API was scheduled for removal in kernel 2.6.35.

The vtx device nodes have been superseded by vbi device nodes
for many years. No applications exist that use the vtx support.
Of the two i2c drivers that actually support this API the saa5249
has been impossible to use for a year now and no known hardware
that supports this device exists. The saa5246a is theoretically
supported by the old mxb boards, but it never actually worked.

In summary: there is no hardware that can use this API and there
are no applications actually implementing this API.

The vtx support still reserves minors 192-223 and we would really
like to reuse those for upcoming new functionality. In the unlikely
event that new hardware appears that wants to use the functionality
provided by the vtx API, then that functionality should be build
around the sliced VBI API instead.

7a569f524d V4L/DVB: IR/streamzap: functional in-kernel decoding
This patch makes in-kernel decoding with the stock Streamzap PC Remote
work out of the box. There are quite a few things going on in this
patch, all related to getting this working:

1) I had to enable reporting of a long space at the end of each signal,
   or I had weird buffering and keybounce issues.

2) The keymap has been reworked slightly to match actual decoded values,
   the first edition was missing the pre-data bits present in the lirc
   config file for this remote.

3) There's a whole new decoder included, specifically for the
   not-quite-RC5 15-bit protocol variant used by the Streamzap PC
   Remote. The decoder, while usable with other recievers (tested with
   an mceusb receiver), will only be loaded by the streamzap driver, as
   its likely not of use in almost all other situations. This can be
   revisited if/when all keytable loading (and disabling of unneeded
   protocol decoder engines) is moved to userspace, but for now, I think
   this makes the most sense.

Note that I did try to enable handling the streamzap RC5-ish protocol in
the current RC5 decoder, but there's no particularly easy way to tell if
its 14-bit RC5 or 15-bit Streamzap until we see bit 14, and even then,
in testing an attempted decoder merge, only 2/3 of the keys were
properly recognized as being the 15-bit variant and decoded correctly,
the rest were close enough to compliant with 14-bit that they were
decoded as such (but they have overlap with one another, and thus we
can't just shrug and use the 14-bit decoded values).

Also of note in this patch is the removal of the streamzap driver's
internal delay buffer. Per discussion w/Christoph, it shouldn't be
needed by lirc any longer anyway, and it doesn't seem to make any
difference to the in-kernel decoder engine. That being the case, I'm
yanking it all out, as it greatly simplifies the driver code.

1f33de0f8b V4L/DVB: gspca_xirlink_cit: New gspca subdriver replacing v4l1 usbvideo/ibmcam.c
The old usbvideo ibmcam driver needs to be replaced with a v4l2 driver
preferably using the gspca webcam framework rather then the old usbvideo
framework.

This new gspca sub driver sets a first step in that direction. The ibmcam
driver supports 4 different model webcams. This new driver (for now) only
supports Model 3 cameras, as my test cam is a Model 3 cam, or so I thought.

Upon reading:
http://www.linux-usb.org/ibmcam/
I learned that the IBM Netcamera Pro I have even though having the same
usb id and the same bcd version is different from the Model 3 cameras
supported by the ibmcam driver. So this new gscpa subdriver supports Model 3
cameras (untested), and the IBM Netcamera Pro. Currently use with the
IBM Netcamera Pro requires a module parameter. I hope to be able to
autodetect which is which in the future.

3e645d6b48 v4l1: fix 32-bit compat microcode loading translation
The compat code for the VIDIOCSMICROCODE ioctl is totally buggered.
It's only used by the VIDEO_STRADIS driver, and that one is scheduled to
staging and eventually removed unless somebody steps up to maintain it
(at which point it should use request_firmware() rather than some magic
ioctl).  So we'll get rid of it eventually.

But in the meantime, the compatibility ioctl code is broken, and this
tries to get it to at least limp along (even if Mauro suggested just
deleting it entirely, which may be the right thing to do - I don't think
the compatibility translation code has ever worked unless you were very
lucky).

2fc11536cf V4L/DVB: videobuf-dma-sg: set correct size in last sg element
This fixes a nasty memory corruption bug when using userptr I/O.
The function videobuf_pages_to_sg() sets up the scatter-gather list for the
DMA transfer to the userspace pages. The first transfer is setup correctly
(the size is set to PAGE_SIZE - offset), but all other transfers have size
PAGE_SIZE. This is wrong for the last transfer which may be less than PAGE_SIZE.

Most, if not all, drivers will program the boards DMA engine correctly, i.e.
even though the size in the last sg element is wrong, they will do their
own size calculations and make sure the right amount is DMA-ed, and so seemingly
prevent memory corruption.

However, behind the scenes the dynamic DMA mapping support (in lib/swiotlb.c)
may create bounce buffers if the memory pages are not in DMA-able memory.
This happens for example on a 64-bit linux with a board that only supports
32-bit DMA.

These bounce buffers DO use the information in the sg list to determine the
size. So while the DMA engine transfers the correct amount of data, when the
data is 'bounced' back too much is copied, causing buffer overwrites.

The fix is simple: calculate and set the correct size for the last sg list
element.

29d834912b V4L/DVB: Fix regression for BeholdTV Columbus
Some time a go our customers wrote me about problem with our TV card
BeholdTV Columbus. It's PCMCIA TV card for notebook.
As I understand v4l has some regression with autodetect address of tuners.
I can set incorrect I2C address and had report about detect tuner. No any TV of course.
When I set correct tuner type and I2C address of the tuners all works well.

23e64d5585 V4L/DVB: saa7164: move dereference under NULL check
The original code dereferenced "port" before checking it for NULL.  I
moved the test down below the check.  Also I changed the comparisons a
little so people wouldn't get confused and think "port" and "buf" were
ints instead of pointers.  (Probably that's what lead to this issue in
the first place.)

There is only one caller for this function and it passes non-NULL
pointers, so this is essentially a cleanup rather than a bugfix.

We dereference "maskptr" unconditionally at the start of the function
and also inside the call to parse_tlist() towards the end of the
function.  This function is called from store_val_any() and it always
passes a non-NULL pointer.

Those breakages seem to be caused by two bad things at IR_CORE Kconfig:

1) cx23885 is using select for IR_CORE;
2) the dvb-usb and sms dependency for IR_CORE were missing.

While here, allow users to un-select IR.

Here a small patch to get a TwinHan VT DST DVB-T card working with
kernels >= 2.6.32. Analogously to
http://linuxtv.org/hg/v4l-dvb/rev/0e735b509163 I had to:

"Fill in the .caps field in struct dst_dvbt_ops (around line 1763) with
all the supported QAM modulation methods to match the capabilities of
the card as implemented in function dst_set_modulation (around line
502). Note that beginning with linux kernel version 2.6.32 the
modulation method is checked (by function dvb_frontend_check_parameters
in file drivers/media/dvb/dvb-core/dvb_frontend.c) and thus tuning fails
if you use a modulation method that is not present in the .caps field."

Since this module is also used by drivers that are not yet converted, the old
and new code have to co-exist.

The source is split into three parts: a common part at the top, which is used
by both old and new code, then the old code followed by the new control
framework implementation. This new code is much more readable (and shorter!)
than the original code.

Once all bridge drivers that use this are converted the old code can be
deleted.

in v4l2-ctrls.c. This new function doesn't use the v4l2_queryctrl
struct anymore, which makes it more general.

The remainder of v4l2-ctrls.c is all new. Highlights include:

- No need to implement VIDIOC_QUERYCTRL, QUERYMENU, S_CTRL, G_CTRL,
  S_EXT_CTRLS, G_EXT_CTRLS or TRY_EXT_CTRLS in either bridge drivers
  or subdevs. New wrapper functions are provided that can just be plugged in.
  Once everything has been converted these wrapper functions can be removed as well.

- When subdevices are added their controls can be automatically merged
  with the bridge driver's controls.

- Most drivers just need to implement s_ctrl to set the controls.
  The framework handles the locking and tries to be as 'atomic' as possible.

- Ready for the subdev device nodes: the same mechanism applies to subdevs
  and their device nodes as well. Sub-device drivers can make controls
  local, preventing them from being merged with bridge drivers.

- Takes care of backwards compatibility handling of VIDIOC_S_CTRL and
  VIDIOC_G_CTRL. Handling of V4L2_CID_PRIVATE_BASE is fully transparent.
  CTRL_CLASS controls are automatically added.

Added this info to Kconfig and mt9m111.c, some comment cleanup,

Driver is fully compatible to mt9m131 which has only additional functions
compared to mt9m111. Those aren't used anyway at the moment.

9bde9f263e V4L/DVB: uvcvideo: Drop corrupted compressed frames
Corrupted video frames are dropped by default by the driver for
uncompressed formats. Data corruption is not less problematic for
compressed formats, so frame drop should be enabled by default for those
formats as well.

Mark buffers as faulty when an isochronous packet loss is detected for
any format, or when the buffer length doesn't match the image size for
uncompressed formats. Drop erroneous buffers regardless of whether the
format is compressed or uncompressed.
