35ea11ff84 V4L/DVB (8430): videodev: move some functions from v4l2-dev.h to v4l2-common.h or v4l2-ioctl.h
The functions in a header should not belong to another module. The prio functions
belong to v4l2-common.c, so move them to v4l2-common.h.

The ioctl functions belong to v4l2-ioctl.c, so create a new v4l2-ioctl.h header
and move those functions to it.

8efdbde647 [CIFS] break ATTR_SIZE changes out into their own function
Move the code that handles ATTR_SIZE changes to its own function. This
makes for a smaller function and reduces the level of indentation.

b4942af650 net: Update entry in af_family_clock_key_strings
In the merge phase of the CAN subsystem the 
af_family_clock_key_strings[] have been added to sock.c in commit 
443aef0edd 
(lockdep: fixup sk_callback_lock annotation). This trivial patch adds 
the missing name for address family 29 (AF_CAN).

5b3ab1dbd4 netdev: Remove warning from __netif_schedule().
It isn't helping anything and we aren't going to be able to change all
the drivers that do queue wakeups in strange situations.

Just letting a noop_qdisc get scheduled will work because when
qdisc_run() executes via net_tx_work() it will simply find no packets
pending when it makes the ->dequeue() call in qdisc_restart.

e81cf44428 V4L/DVB (8433): Fix macro name at z0194a.h
As reported by Hans Verkuil:

In file included from /home/v4l/master/v4l/dw2102.c:14:
/home/v4l/master/v4l/z0194a.h:93: error: 'STV0229_LOCKOUTPUT_1' undeclared here (not in a function)

This is due to some typos that were fixed on stv0299.

This patch renames it in accord with that fix.

22a04f1063 V4L/DVB (8429): videodev: renamed 'class_dev' to 'dev'
The class_dev field is a normal device, not a class device. This is very
confusing and now that the old 'dev' field has been renamed to 'parent'
we can rename 'class_dev' to just 'dev'.

27a5e6d3fc V4L/DVB (8427): videodev: split off the ioctl handling into v4l2-ioctl.c
videodev.c became top-heavy so all the ioctl processing has been split off
into v4l2-ioctl.c. This means videodev.c is back to its original purpose:
creating and registering v4l devices.

Since videodev.c and v4l2-ioctl.c should still remain one module (as least
for now) I also had to rename videodev.c to v4l2-dev.c to prevent a
circular dependency when building a videodev.ko module. This is not a bad
thing, since the source and header now have the same name. And the v4l2-
prefix is useful to see which sources are generic v4l2 support code.

09e50d55a9 lockdep: annotate cifs in-kernel sockets
Put CIFS sockets in their own class to avoid some lockdep warnings. CIFS
sockets are not exposed to user-space, and so are not subject to the
same deadlock scenarios.

A similar change was made a couple of years ago for RPC sockets in commit
ed07536ed6.

This patch should prevent lockdep false-positives like this one:

6aabcdffd1 Input: serio - offload resume to kseriod
When resuming AUX ports psmouse driver calls psmouse_extensions()
to determine if the attached mouse is still the same, which may take
a while to complete for generic mice. Offload the resume process to
kseriod so the rest of the system may continue resuming without
waiting for the mouse.

It is important that drive->pc_callback is set prior to enabling IRQs on the
device since this is called from the IRQ handler. Otherwise it hurts as I learnt
the hard way from the several "Kernel panic - not synching: Fatal exception in
interrupt" during the weekend :).

Refrain from carrying the callback ptr with every packet command since the
callback function is only one anyways. ide_drive_t is probably not the most
suitable place for it right now but is the more sane solution. Besides, these
structs are going to be reorganized anyways during the generic ide rewrite.
