V4L/DVB: v4l videobuf: remove mmap_free callback
Remove the mmap_free callback from struct videobuf_qtype_ops. All implementations of this callback do the same trivial check: return -EBUSY if any buffer is mmapped. That can also be tested in the videobuf core. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
