| |
From: Markus Elfring <elfring@users.sourceforge.net> Date: Sun, 23 Nov 2014 15:15:29 +0100
The backlight_device_unregister() 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.
