From f35cbe6a178e94d3fc290f414aa421f81ac76069 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Wed, 20 Jul 2016 17:54:32 +0200 Subject: [PATCH] drm/atomic: Delete an unnecessary check before drm_property_unreference_blob() The drm_property_unreference_blob() 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.
