For m2m devices the vdev->queue lock was always taken instead of the
lock for the specific capture or output queue. Now that we pushed
the locking down into __video_do_ioctl() we can pick the correct
lock and potentially improve the performance of m2m devices.

If dev_debug was active, then the code could return without unlocking the

The ioctl serialization mutex (vdev->lock or q->lock for vb2 queues)
was taken at the highest level in v4l2-dev.c. This prevents more
fine-grained locking since at that level we cannot examine the ioctl
arguments, we can only do that after video_usercopy is called.
So push the locking down to __video_do_ioctl() and subdev_do_ioctl_lock().
This also allows us to make a few functions in v4l2-ioctl.c static and
video_usercopy() is no longer exported.
The locking scheme is not changed by this patch, just pushed down.

Don't duplicate the buffer type checks in enum/g/s/try_fmt.
The check_fmt function does that already.
It is hard to keep the checks in sync for all these functions and
in fact the check for VBI was wrong in the _fmt functions as it
allowed SDR types as well. This caused a v4l2-compliance failure
for /dev/swradio0 using vivid.
This simplifies the code and keeps the check in one place and
fixes the SDR/VBI bug.

The type field in struct v4l2_selection is supposed to never use the
_MPLANE variants. E.g. if the driver supports V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE,
then userspace should still pass V4L2_BUF_TYPE_VIDEO_CAPTURE.
The reasons for this are lost in the mists of time, but it is really
annoying. In addition, the exynos drivers didn't follow this rule and
instead expected the _MPLANE type.
To fix that code is added to the v4l2 core that maps the _MPLANE buffer
types to their regular equivalents before calling the driver.
Effectively this allows for userspace to use either _MPLANE or the regular
buffer type. This keeps backwards compatibility while making things easier
for userspace.
Since drivers now never see the _MPLANE buffer types the exynos drivers
had to be adapted as well.

There are multiple places where arrays or otherwise variable sized
buffer are allocated through V4L2 core code, including things like
controls, memory pages, staging buffers for ioctls and so on. Such
allocations can potentially require an order > 0 allocation from the
page allocator, which is not guaranteed to be fulfilled and is likely to
fail on a system with severe memory fragmentation (e.g. a system with
very long uptime).
Since the memory being allocated is intended to be used by the CPU
exclusively, we can consider using vmalloc() as a fallback and this is
exactly what the recently merged kvmalloc() helpers do. A kmalloc() call
is still attempted, even for order > 0 allocations, but it is done
with __GFP_NORETRY and __GFP_NOWARN, with expectation of failing if
requested memory is not available instantly. Only then the vmalloc()
fallback is used. This should give us fast and more reliable allocations
even on systems with higher memory pressure and/or more fragmentation,
while still retaining the same performance level on systems not
suffering from such conditions.
While at it, replace explicit array size calculations on changed
allocations with kvmalloc_array().
Purposedly not touching videobuf1, as it is deprecated, has only few
users remaining and would rather be seen removed instead.

Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.

adjusted if needed.

- Add V4L2_CAP_TOUCH to indicate device is a touch device
Add formats:
- V4L2_TCH_FMT_DELTA_TD16 for signed 16-bit touch deltas
- V4L2_TCH_FMT_DELTA_TD08 for signed 16-bit touch deltas
- V4L2_TCH_FMT_TU16 for unsigned 16-bit touch data

- Add a check for the case that both the cropcap and g_selection ops
are NULL. This shouldn't happen, but I feel happier if the code
guards against this.
- If g_selection exists, then ignore ENOTTY and ENOIOCTLCMD error
codes from cropcap. Just assume square pixelaspect ratio in that
case. This situation can happen if the bridge driver's cropcap op
calls the corresponding subdev's op. So the cropcap ioctl is set,
but it might return ENOIOCTLCMD anyway. In the past this would
just return an error which is wrong.
- Call cropcap first and let g_selection overwrite the bounds and
defrect. This safeguards against subdev cropcap implementations
that set those rectangles as well. What g_selection returns has
priority over what such cropcap implementations return.
