From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> Date: Wed, 20 Jul 2016 17:54:32 +0200 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.
