    Subject[PATCH] GPU-DRM-IMX: Delete an unnecessary check before drm_fbdev_cma_restore_mode()
    From: Markus Elfring <elfring@users.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.
