    Subject[PATCH 1/1] DRM-tilcdc: Deletion of an unnecessary check before the function call "drm_fbdev_cma_hotplug_event"
    From: Markus Elfring <elfring@users.sourceforge.net>
    Date: Wed, 19 Nov 2014 17:05:20 +0100

    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.
