[PATCH] GPU-DRM-sun4i: Delete an unnecessary check before drm_fbdev_cma_hotplug_event()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Wed, 20 Jul 2016 18:32:34 +0200

The drm_fbdev_cma_hotplug_event() 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.
