Now that drivers/media/video/v4l2-ioctl.c fills cap->version:
	case VIDIOC_QUERYCAP:
	{
		struct v4l2_capability *cap = (struct v4l2_capability *)arg;

		if (!ops->vidioc_querycap)
			break;

		cap->version = LINUX_VERSION_CODE;

V4L2 drivers that use video_ioctl2() shouldn't initialize it anymore.

The V4L2 core now fills it automatically, so drivers shouldn't touch on
cap->version anymore.

Fixes a regression in VIDIOC_QUERYMENU introduced when the __s64 value
field was added to the union. On a 64-bit system this will change the
size of this v4l2_querymenu structure from 44 to 48 bytes, thus
breaking the ABI. By adding the packed attribute it is working again.

au8522_dig.o and au8522_decoder.o function independentantly
of each other, each for a different hardware function using
a different software subsystem api, each with its own set
of subsystem module dependencies.

Since these drivers do not depend on each other, and it is
in fact possible to build hardware designs using one function
and not the other, lets split this module into two, allowing
system integrators to enable the hardware without dragging in
undesired dependencies.

`clipcount' is from userspace and thus needs validation.  Otherwise,
a large `clipcount' could overflow the vmalloc() size, leading to
out-of-bounds access.

| zoran_s_fmt_vid_overlay()
| __video_do_ioctl()
| video_ioctl2()

firmware - comments just stating that add no value.
