2ff0f16ded [media] adv7842: Disable access to EDID DDC lines before chip power up
In core_init make sure access to EDID DDC lines are disabled
before chip is powered up. Also DISABLE_AUTO_EDID before power up.
The correct setting is applied later when setting the EDID.
Some sources (MAC) kept on reading EDID even when Hotplug was low
and in the short period in core_init before the DDC lines was enabled
read a corrupt EDID.

ba2d35c14b [media] v4l2-ioctl.c: fix sparse __user-related warnings
Fix the use of __user in the check_array_args() prototype: instead of
using 'void * __user *' you should use 'void __user **' for sparse to
understand this correctly.

This also required the use of __force in the '*kernel_ptr = user_ptr'
assignment.

Also replace a wrong cast (void *) with the correct one (void **)
in check_array_args().

This fixes these sparse warnings:

These are caused by the call*op defines which do something like this:

        (ops->op) ? ops->op(args) : 0

which is OK as long as op is not a void function, because in that case one part
of the conditional expression returns void, the other an integer. Hence the sparse
errors.

I've replaced this by introducing three variants of the call_ macros:
call_*op for int returns, call_void_*op for void returns and call_ptr_*op for
pointer returns.

That's the bad news. The good news is that the fail_*op macros could be removed
since the call_*op macros now have enough information to determine if the op
succeeded or not and can increment the op counter only on success. This at least
makes it more robust w.r.t. future changes.

877ed14306 [media] Prefer gspca_sonixb over sn9c102 for all devices
The sn9c102 driver is deprecated. It was moved to staging in
anticipation of its removal in a future kernel version. However, USB
devices 0C45:6024 and 0C45:6025 are still handled by sn9c102 when
both sn9c102 and gspca_sonixb are enabled.

We must migrate all the users of these devices to the gspca_sonixb
driver now, so that it gets sufficient testing before the sn9c102
driver is finally phased out.

c1d1e40b8b [media] media: davinci: vpfe: make sure all the buffers unmapped and released
this patch makes sure that it terminates if any IO in
progress and also makes sure that all the buffers are unmapped.
It was observed that with several runs of application the application
sometimes failed to allocate memory, This patch makes sure it
all the buffers are released.

Using kmemleak it was found that buffer were not released, this patch
fixes following issue,

 echo scan > /sys/kernel/debug/kmemleak

      memleak: 3 new suspected memory leaks (see /sys/kernel/debug/kmemleak)

e6ba3db104 [media] media: davinci: vpif_capture: fix releasing of active buffers
from commit-id: b3379c6201
"vb2: only call start_streaming if sufficient buffers are queued"
the vb2 framework warns on (WARN_ON()) if all the active buffers
are not released when streaming is stopped, initially the vb2 silently
released the buffer internally if the buffer was not released by
the driver.
Also this patch moves the disabling of interrupts from relase() callback
to stop_streaming() callback as which needs to be done ideally.

This patch fixes following issue:

5269fef77e [media] v4l: ti-vpe: Set correct field parameter for output and capture buffers
The vpe driver wasn't setting the correct field parameter for dequed CAPTURE
type buffers for the case where the captured output is progressive.

Set the field to V4L2_FIELD_NONE for the completed destination buffers when
the captured output is progressive.

For OUTPUT type buffers, a queued buffer's field is forced to V4L2_FIELD_NONE
if the pixel format(configured through s_fmt for the buffer type
V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE specifies) the field type isn't interlaced.
If the pixel format specified was V4L2_FIELD_ALTERNATE, and the queued buffer's
field isn't V4L2_FIELD_TOP or V4L2_FIELD_BOTTOM, the vb2 buf_prepare op returns
an error.

This ensures compliance, and that the dequeued output and captured buffers
contain the field type that the driver used internally.

The vpe output and capture queues are initially configured to default values in

772a7b7ae1 [media] v4l: ti-vpe: Use video_device_release_empty
The video_device struct is currently embedded in the driver data struct vpe_dev.
A vpe_dev instance is allocated by the driver, and the memory for the vfd is a
part of this struct.

The v4l2 core, however, manages the removal of the vfd region, through the
video_device's .release() op, which currently is the helper
video_device_release. This causes memory corruption, and leads to issues when
we try to re-insert the vpe module.

Use the video_device_release_empty helper function instead.

db476163da [media] v4l: ti-vpe: Make sure in job_ready that we have the needed number of dst_bufs
VPE has a ctrl parameter which decides how many mem to mem transactions the
active job from the job queue can perform.

The driver's job_ready() made sure that the number of ready source buffers are
sufficient for the job to execute successfully. But it didn't make sure if
there are sufficient ready destination buffers in the capture queue for the
VPE output.

If the time taken by VPE to process a single frame is really slow, then it's
possible that we don't need to imply such a restriction on the dst queue, but
really fast transactions(small resolution, no de-interlacing) may cause us to
hit the condition where we don't have any free buffers for the VPE to write on.

Add the extra check in job_ready() to make sure we have the sufficient amount
of destination buffers.

The original patch ignored the fact that NEC32 scancodes are generated not
only in the NEC raw decoder but also directly in some drivers. Whichever
approach is chosen it should be consistent across drivers and this patch
needs more discussion.

Furthermore, I'm convinced that we have to stop playing games trying to

which byte is the MSB, etc).

Pull media updates from Mauro Carvalho Chehab:
 "The main set of series of patches for media subsystem, including:
   - document RC sysfs class
   - added an API to setup scancode to allow waking up systems using the
     Remote Controller
   - add API for SDR devices.  Drivers are still on staging
   - some API improvements for getting EDID data from media
     inputs/outputs
   - new DVB frontend driver for drx-j (ATSC)
   - one driver (it913x/it9137) got removed, in favor of an improvement
     on another driver (af9035)
   - added a skeleton V4L2 PCI driver at documentation
   - added a dual flash driver (lm3646)
   - added a new IR driver (img-ir)
   - added an IR scancode decoder for the Sharp protocol
   - some improvements at the usbtv driver, to allow its core to be
     reused.
   - added a new SDR driver (rtl2832u_sdr)
   - added a new tuner driver (msi001)
   - several improvements at em28xx driver to fix PM support, device
     removal and to split the V4L2 specific bits into a separate
     sub-driver
   - one driver got converted to videobuf2 (s2255drv)
   - the e4000 tuner driver now follows an improved binding model
   - some fixes at V4L2 compat32 code
   - several fixes and enhancements at videobuf2 code
   - some cleanups at V4L2 API documentation
   - usual driver enhancements, new board additions and misc fixups"

[ NOTE! This merge effective drops commit 4329b93b28 ("of: Reduce
  indentation in of_graph_get_next_endpoint").

  The of_graph_get_next_endpoint() function was moved and renamed by
  commit fd9fdb78a9 ("[media] of: move graph helpers from
  drivers/media/v4l2-core to drivers/of").  It was originally called
  v4l2_of_get_next_endpoint() and lived in the file
  drivers/media/v4l2-core/v4l2-of.c.

  In that original location, it was then fixed to support empty port
  nodes by commit b9db140c1e ("[media] v4l: of: Support empty port
  nodes"), and that commit clashes badly with the dropped "Reduce
  intendation" commit.  I had to choose one or the other, and decided
  that the "Support empty port nodes" commit was more important ]

Pull compat time conversion changes from Peter Anvin:
 "Despite the branch name this is really neither an x86 nor an
  x32-specific patchset, although it the implementation of the
  discussions that followed the x32 security hole a few months ago.

  This removes get/put_compat_timespec/val() and replaces them with
  compat_get/put_timespec/val() which are savvy as to the current status
  of COMPAT_USE_64BIT_TIME.

  It removes several unused and/or incorrect/misleading functions (like
  compat_put_timeval_convert which doesn't in fact do any conversion)
  and also replaces several open-coded implementations what is now
  called compat_convert_timespec() with that function"
