[media] cx231xx-417: share ioctls with cx231xx-video
Share tuner, frequency, debug and input ioctls with cx231xx-video. These are all shared resources, so no need to implement them again. [mchehab@redhat.com: Fix merge conflict and a checkpatch issue] Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
