eb9910894d HID: fix lock imbalance in hiddev
Don't forget to unlock_kernel() in hiddev_ioctl_usage().
Added in 7961df1681
(HID: Switch hiddev to unlocked_ioctl).

Corresponing sparse warning:
drivers/hid/usbhid/hiddev.c:515:10: warning: context imbalance in 'hiddev_ioctl_usage': wrong count at exit
drivers/hid/usbhid/hiddev.c:515:10:    context 'kernel_lock': wanted 0, got 1

93c10132a7 HID: move connect quirks
Move connecting from usbhid to the hid layer and fix also hidp in
that manner.
This removes all the ignore/force hidinput/hiddev connecting quirks.

7961df1681 HID: Switch hiddev to unlocked_ioctl
Push down the BKL. In some cases compat_ioctl already doesn't take the
BKL so we don't either. Some of the locking here seems already dubious
and object lifetimes want documenting

cf2a299e48 HID: fix build failure in hiddev_ioctl with gcc 3.2
Fix build failure in hiddev_ioctl with gcc 3.2:
http://bugzilla.kernel.org/show_bug.cgi?id=10121

The trick is to move the handling of ioctls which need to allocate
memory to separate functions.

bb6c8d8fa9 HID: hiddev: Add 32bit ioctl compatibilty
The hiddev driver currently lacks 32bit ioctl compatibility, so
if you're running with a 64bit kernel and 32bit userspace, it won't
work.

I'm pretty sure that the only thing missing is a compat_ioctl
implementation as all structs have fixed size fields.

With this change I can use revoco to configure my MX Revolution mouse.

58037eb961 HID: make debugging output runtime-configurable
There have been many reports recently about broken HID devices, the
diagnosis of which required users to recompile their kernels in order
to be able to provide debugging output needed for coding a quirk for
a particular device.

This patch makes CONFIG_HID_DEBUG default y if !EMBEDDED and makes it
possible to control debugging output produced by HID code by supplying
'debug=1' module parameter.

cdcb44e87b USB HID: hiddev - fix race between hiddev_send_event() and hiddev_release()
There is a small race window in which hiddev_release() could corrupt the
list that is being processed for new event in hiddev_send_event().
Synchronize the operations over this list.
