05efa71bdc [media] media: add a VEU MEM2MEM format conversion and scaling driver
Video Engine Unit (VEU) is an IP block, found in multiple SuperH and ARM-
based sh-mobile and r-mobile SoCs, capable of processing video data. It
can perform colour-space conversion, scaling and several filtering
transformations. This patch adds an initial implementation of a mem2mem
V4L2 driver for VEU. So far only conversion from NV12 to RGB565 is
supported. Further functionality shall be added in the future.
This driver is based on a VEU vidix driver by Magnus Damm.

71d5e7af12 [media] omap_vout: Drop overlay format enumeration
Enumerating formats for output overlays doesn't make sense, as the pixel
format is defined by the display API, not the V4L2 API. Drop the
vidioc_enum_fmt_vid_overlay ioctl operation.

8a4e786660 [media] au0828: remove forced dependency of VIDEO_AU0828 on VIDEO_V4L2
This patch removes the dependendency of VIDEO_AU0828 on VIDEO_V4L2 by
creating a new Kconfig option, VIDEO_AU0828_V4L2, which enables analog
video capture support and depends on VIDEO_V4L2 itself.
With VIDEO_AU0828_V4L2 disabled, the driver will only support digital
television and will not depend on the v4l2-core. With VIDEO_AU0828_V4L2
enabled, the driver will be built with the analog v4l2 support included.
By default, the VIDEO_AU0828_V4L2 option will be set to Y, so as to
preserve the original behavior.

605a410325 [media] soc_camera: fix VIDIOC_S_CROP ioctl
Sometimes VIDIOC_S_CROP ioctl doesn't work, soc-camera driver reports:
soc-camera-pdrv soc-camera-pdrv.0: S_CROP denied: getting current crop failed
The VIDIOC_G_CROP documentation states that the type field needs to be
set to the respective buffer type when querying, so the check in .g_crop()
of the subdevices returns -EINVAL if the type is not set properly. Here the
uninitialized local variable 'current_crop' is passed to the .g_crop() and
this leads to the observed error. Initialize the type field of the local
'current_crop' before get_crop call.

16427faf28 [media] tm6000: Add parameter to keep urb bufs allocated
On systems where it cannot be assured that enough continous memory is available
all the time it can be very useful to only allocate the memory once when it is
needed the first time. Afterwards the initially allocated memory will be
reused, so it is ensured that the memory will stay available until the driver
is unloaded.

d3594ea2b3 Merge branch 'block-dev'
Merge 'block-dev' branch.

I was going to just mark everything here for stable and leave it to the
3.8 merge window, but having decided on doing another -rc, I migth as
well merge it now.

This removes the bd_block_size_semaphore semaphore that was added in
this release to fix a race condition between block size changes and
block IO, and replaces it with atomicity guaratees in fs/buffer.c
instead, along with simplifying fs/block-dev.c.

This removes more lines than it adds, makes the code generally simpler,
and avoids the latency/rt issues that the block size semaphore
introduced for mount.

I'm not happy with the timing, but it wouldn't be much better doing this
during the merge window and then having some delayed back-port of it
into stable.

* block-dev:
  blkdev_max_block: make private to fs/buffer.c
  direct-io: don't read inode->i_blkbits multiple times
  blockdev: remove bd_block_size_semaphore again

1430e17844 drivers/rtc/rtc-tps65910.c: fix invalid pointer access on _remove()
The tps65910_rtc data is registered as the platform driver data in
_probe(= ).  Therefore the tps65910_rtc should be used on unregistering
the rtc device.  And device pointer should be retrieved from the
platform_device structure.

This patch fixes the below oops:

1e8b33328a blockdev: remove bd_block_size_semaphore again
This reverts the block-device direct access code to the previous
unlocked code, now that fs/buffer.c no longer needs external locking.

With this, fs/block_dev.c is back to the original version, apart from a
whitespace cleanup that I didn't want to revert.

Race between bonding_store_slaves_active() and slave manipulation
 functions. The bond_for_each_slave use in bonding_store_slaves_active()
 is not protected by any synchronization mechanism.
 NULL pointer dereference is easy to reach.
 Fixed by acquiring the bond->lock for the slave walk.

fbb0c41b81 bonding: fix miimon and arp_interval delayed work race conditions
First I would give three observations which will be used later.
Observation 1: if (delayed_work_pending(wq)) cancel_delayed_work(wq)
 This usage is wrong because the pending bit is cleared just before the
 work's fn is executed and if the function re-arms itself we might end up
 with the work still running. It's safe to call cancel_delayed_work_sync()
 even if the work is not queued at all.
Observation 2: Use of INIT_DELAYED_WORK()
 Work needs to be initialized only once prior to (de/en)queueing.
Observation 3: IFF_UP is set only after ndo_open is called

Related race conditions:
1. Race between bonding_store_miimon() and bonding_store_arp_interval()
 Because of Obs.1 we can end up having both works enqueued.
2. Multiple races with INIT_DELAYED_WORK()
 Since the works are not protected by anything between INIT_DELAYED_WORK()
 and calls to (en/de)queue it is possible for races between the following
 functions:
 (races are also possible between the calls to INIT_DELAYED_WORK()
  and workqueue code)
 bonding_store_miimon() - bonding_store_arp_interval(), bond_close(),
			  bond_open(), enqueued functions
 bonding_store_arp_interval() - bonding_store_miimon(), bond_close(),
				bond_open(), enqueued functions
3. By Obs.1 we need to change bond_cancel_all()

Bugs 1 and 2 are fixed by moving all work initializations in bond_open
which by Obs. 2 and Obs. 3 and the fact that we make sure that all works
are cancelled in bond_close(), is guaranteed not to have any work
enqueued.
Also RTNL lock is now acquired in bonding_store_miimon/arp_interval so
they can't race with bond_close and bond_open. The opposing work is
cancelled only if the IFF_UP flag is set and it is cancelled
unconditionally. The opposing work is already cancelled if the interface
is down so no need to cancel it again. This way we don't need new
synchronizations for the bonding workqueue. These bugs (and fixes) are
tied together and belong in the same patch.
Note: I have left 1 line intentionally over 80 characters (84) because I
      didn't like how it looks broken down. If you'd prefer it otherwise,
      then simply break it.

Pull networking fixes from David Miller:
 "Some more fixes trickled in over the past few days:

   1) PIM device names can overflow the IFNAMSIZ buffer unless we
      properly limit the allowed indexes, fix from Eric Dumazet.

   2) Under heavy load we can OOPS in icmp reply processing due to an
      unchecked inet_putpeer() call.  Fix from Neal Cardwell.

   3) SCTP round trip calculations need to use 64-bit math to avoid
      overflows, fix from Schoch Christian.

   4) Fix a memory leak and an error return flub in SCTP and IRDA
      triggerable by userspace.  Fix from Tommi Rantala and found by the
      syscall fuzzer (trinity).

   5) MLX4 driver gives bogus size to memcpy() call, fix from Amir
      Vadai.

   6) Fix length calculation in VHOST descriptor translation, from
      Michael S Tsirkin.

   7) Ambassador ATM driver loops forever while loading firmware, fix
      from Dan Carpenter.

   8) Over MTU packets in openvswitch warn about wrong device, fix from
      Jesse Gross.

   9) Netfilter IPSET's netlink code can overrun a string buffer because
      it's not properly limited to IFNAMSIZ.  Fix from Florian Westphal.

  10) PCAN USB driver sets wrong timestamp in SKB, from Oliver Hartkopp.

  11) Make sure the RX ifindex always has a valid value in the CAN BCM
      driver, even if we haven't received a frame yet.  Fix also from
      Oliver Hartkopp."
