From d37e2a150e42bac8c297430c080e3bdf5d7084a7 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Fri, 15 Jul 2016 15:23:22 +0200 Subject: [PATCH] drm/rockchip: Delete an unnecessary check before drm_gem_object_unreference_unlocked() The drm_gem_object_unreference_unlocked() 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.
