From 8aa9eb9059f6246b530d664f271e5c32858222ed Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 3 Feb 2015 15:00:25 -0300 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.
