If requests are not supported by the driver, then return EACCES, not
EPERM.
If you attempt to mix queueing buffers directly and using requests,
then EBUSY is returned instead of EPERM: once a specific queueing mode
has been chosen the queue is 'busy' if you attempt the other

Set the capabilities field of v4l2_requestbuffers and v4l2_create_buffers.
The various mapping modes were easy, but for signaling the request capability
a new 'supports_requests' bitfield was added to videobuf2-core.h (and set in
vim2m and vivid). Drivers have to set this

The driver registers the v4l2 subdevice before attempting to power on the
chip and checking its ID. This means that a media device driver that it's
waiting for this subdevice to be bound, will prematurely expose its media
device node to userspace because if something goes wrong the media entity

Instead of returning -ENOENT when a request_fd was not found (VIDIOC_QBUF
and VIDIOC_G/S/TRY_EXT_CTRLS), we now return -EINVAL. This is in line
with what we do when invalid dmabuf fds are passed to e.g. VIDIOC_QBUF.
Also document that EINVAL is returned for invalid m.fd

When getting control values from a completed request, we have

The initial sizeimage for the compressed decoder output was wrong.
The size of the output was incorrectly used to calculate the image
size, that should have been the size of the capture.
Rework the code to fix this.
