i've double-checked that there are no other video drivers affected by
this problem:

$ cd drivers/media/
$ grep -C 10 videobuf_mmap_setup `grep -l mutex_lock */*.c */*/*.c */*/*/*.c`

video/videobuf-core.c- mutex_lock(&q->lock);
video/videobuf-core.c- mutex_lock(&q->lock);
video/bt8xx/bttv-driver.c- mutex_lock(&fh->cap.lock);

so only bttv-driver.c was affected, at first sight.
