V4L/DVB (8636): v4l2: add v4l2_ctrl_get_name control support function.
Add function that returns the control name. Allows this to be used in places where the normal v4l2_ctrl_query_fill() function cannot be used (e.g. uvc). Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
