From dc3583c86ae08cf89917e1874ae29b5cd651044e Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Fri, 22 Jul 2016 14:14:54 +0200 Subject: [PATCH] drm/qxl: 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.
