From 8a8e411dc0b57e7f930b554b3aa9309b60662db6 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sun, 23 Nov 2014 15:15:29 +0100 Subject: [PATCH] video: mx3fb: Deletion of an unnecessary check before the function call "backlight_device_unregister" 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.
