272023df26 mtd: nand: Fix memory leak on txx9ndfmc probe failure.
Commit 81933046ef ('mtd: Fix handling of
mtdname in txx9ndfmc.c') introduced a potential memory leak. The
'mtdname' member of the private data structure is now allocated
separately, but was not freed on certain error paths.

Fix that, and make things simpler by _always_ allocating it separately
so that we don't need 'if (mtdname != dev_name()) kfree(mtdname);'...
which gets ugly now that we're doing it more than once, and more likely
that we'll get it wrong some time.

f36e20c01a mtd: plat_nand: allow platform to set partitions
Add optional callback to allow platform to initialize partitions.

Static partitions on a nand device could vary depending on the size of the
device.  This patch allows an optional platform callback to be used to
setup this partition information at runtime.

Scan order is:
	1) chip.part_probe_types
	2) chip.set_parts
	3) chip.partitions
	4) full mtd device (fallback for no partitions)

Some of the existing nand drivers could possibly be replaced by the
plat_nand driver by using this patch.  These include autcpu12.c and
ts7250.c drivers.

from the plat_nand driver a hook for read_buf (and also write_buf whilst

Make the DaVinci NAND driver require platform_data with
board-specific configuration.  We can't actually do any
kind of sane job of configuring it otherwise.

Also fix the comment about picking the "best" ECC mode.

We can't do those any more; that relied on knowing what kind
of CPU we're using (they don't all support 4-bit ECC), and
current policy is that drivers not have cpu_is_*() checks.

 - pass on the error code from clk_get()
 - return -ENOMEM in case of failed ioremap()
 - pass on the return value of platform_driver_probe() directly
 - remove excessive printk
 - let command line partition table parsing with mxc_nand name.
   The cmd_line parsing is done via <mtd-id> name that differs

ade92a636f [MTD] [NAND] FSL-UPM: Add wait flags to support board/chip specific delays
The NAND flash on the TQM8548_BE modules requires a short delay after
running the UPM pattern. The TQM8548_BE requires a further short delay
after writing out a buffer. Normally the R/B pin should be checked, but
it's not connected on the TQM8548_BE. The existing driver uses similar
fixed delay points. To manage these extra delays in a more general way,
I introduced the "fsl,ump-wait-flags" property allowing the board-
specific driver to specify various types of extra delay.

9d63287a46 [MTD] [NAND] move gen_nand's probe function to .devinit.text
A pointer to plat_nand_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

a6e6abd575 module: remove module_text_address()
Impact: Replace and remove risky (non-EXPORTed) API

module_text_address() returns a pointer to the module, which given locking
improvements in module.c, is useless except to test for NULL:

1) If the module can't go away, use __module_text_address.
2) Otherwise, just use is_module_text_address().

7a192ec334 platform driver: fix incorrect use of 'platform_bus_type' with 'struct device_driver'
This patch fixes the bug reported in
	http://bugzilla.kernel.org/show_bug.cgi?id=11681.

"Lots of device drivers register a 'struct device_driver' with
the '.bus' member set to '&platform_bus_type'. This is wrong,
since the platform_bus functions expect the 'struct device_driver'
to be wrapped up in a 'struct platform_driver' which provides
some additional callbacks (like suspend_late, resume_early).
The effect may be that platform_suspend_late() uses bogus data
outside the device_driver struct as a pointer pointer to the
device driver's suspend_late() function or other hard to
reproduce failures."(Lothar Wassmann)
