A previous attempt to deal with the upcoming loss of video_set_drvdata() and video_get_drvdata() resulted in logic which causes a circular locking dependency - also known as a deadlock. This changeset attacks the problem in a different manner, using a technique that no longer requires the problematic mutex (or that private global array either).
