Subject: [PATCH] [media] au0828: Delete unnecessary checks before the function
 call "video_unregister_device"

The video_unregister_device() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
