[PATCH] drm/atomic: Delete an unnecessary check before drm_property_unreference_blob()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
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.
