From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> Date: Mon, 24 Nov 2014 22:58:48 +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.
