Date: Sun, 05 Jul 2015 22:00:21 +0200 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: David Airlie <airlied@...ux.ie>, dri-devel@...ts.freedesktop.org CC: Linux Kernel Mailing List <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Julia Lawall <julia.lawall@...6.fr> Subject: [PATCH] GPU-DRM: Delete an unnecessary check before drm_property_unreference_blob() From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Sun, 5 Jul 2015 21:55:10 +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.
