From 851dd75d64dbfc9a97d5109659e82e95d6bbe5bf Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Wed, 13 Jul 2016 18:54:11 +0200 Subject: [PATCH] drm/msm/hdmi: Delete an unnecessary check before the function call "kfree" The kfree() 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.
