Laurent Pinchart d52e238136 [media] v4l: Support extending the v4l2_pix_format structure
The v4l2_pix_format structure has no reserved field. It is embedded in
the v4l2_framebuffer structure which has no reserved fields either, and
in the v4l2_format structure which has reserved fields that were not
previously required to be zeroed out by applications.

To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer
structure, and use the priv field as a magic value to indicate that the
application has set all v4l2_pix_format extended fields and zeroed all
reserved fields following the v4l2_pix_format field in the v4l2_format
structure.

The availability of this API extension is reported to userspace through
the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the
priv field is still set to the magic value at [GS]_FMT return wouldn't
be enough, as older kernels don't zero the priv field on return.

To simplify the internal API towards drivers zero the extended fields
and set the priv field to the magic value for applications not aware of
the extensions.

Lad, Prabhakar 4015bef649 [media] media: davinci: vpif_capture: drop unneeded module params
Remove bogus 'numbuffers' and 'bufsize' module options. The number of buffers and
buffer sizes are determined by VIDIOC_REQBUFS and VIDIOC_S_FMT and the amount of
available memory (in the case of the MMAP stream I/O mode) and not by module
options.

These module params are a left-over from the original montavista code that used
these parameters to pre-allocate the memory needed for the buffers. The code that
allocated those buffers was never upstreamed since by the time the drivers were
added to the kernel the TI cmem module could be used in combination with the
USERPTR mode to reserve and pass physically contiguous memory pointers around.

These days of course CMA is used instead of cmem.

This patch removes these module options altogether since they no longer do what
they originally were designed for. They should never have been part of the
upstreamed code in the first place, so they've been pointless ever since
2.6.32 when this driver first appeared in the mainline kernel.
