I know that patch is a little bit stupid, but at least it seems to kill that "INFO: possible circular locking dependency detected" / DEADLOCK warning reported by lockdep.
Somehow this kind of warnings are very annoying when you don't know it is a "feature". Like what happens to me; I made my first V4L2 driver and then enabled all kind of Kernel debugs to see if there is possible issues. And kaboom, that jumped to out. It took really a some time to figure it is not my module, but coming from v4l core layers.
