Please see patchset on topic "v4l2-dev/ioctl: Add V4L2_CAP_IO_MC" on
linux-media; it's relevant here, too.
Can update in v6 to add device caps V4L2_CAP_IO_MC and remove enum/g/s_input
ioctls.
But, I don't see this patch "v4l2-dev/ioctl: Add V4L2_CAP_IO_MC" on latest
linux-next
It's not merged yet but likely will be very soon.

OK, Will wait and send v6 once I see that patch merged. Thanks Sakari.
