Subject: [PATCH] GPU-DRM-IMX: Delete an unnecessary check before drm_fbdev_cma_restore_mode()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 5 Jul 2015 22:45:23 +0200

The drm_fbdev_cma_restore_mode() 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.
