V4L/DVB (6601): V4L: videobuf-core locking fixes and comments
- Add comments to functions that require that caller hold q->lock - Add __videobuf_mmap_free that doesn't hold q->lock for use within videobuf - Add locking to videobuf_mmap_free - Fix linux/drivers/media/common/saa7146_video.c which was holding lock around videobuf_read_stop - Add locking to functions that operate on a queue - Add videobuf_stop to take care of stopping in both the read and stream case TODO: bttv still has an unsafe call to videobuf_queue_is_busy Signed-off-by: Brandon Philips <bphilips@suse.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
