[PATCH] drm/arcpgu: Delete an unnecessary check before drm_fbdev_cma_hotplug_event()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Fri, 15 Jul 2016 21:52:40 +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.
