[media] v4l2: make vidioc_s_audio const
Write-only ioctls should have a const argument in the ioctl op. Do this conversion for vidioc_s_audio. Adding const for write-only ioctls was decided during the 2012 Media Workshop. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
