V4L/DVB (5842): ivtv: Add locking to ensure stream setup is atomic.
Starting an MPEG and VBI capture simultaneously caused errors in the VBI setup: this setup was done twice when it should be done only for the first stream that is opened. Added a mutex to prevent this from happening. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
