Subject: drm/atmel-hlcdc: Remove unnecessary NULL check
Git-commit: 6c8e54714cc54d080189e42fb40b24dddfe85339
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

drm_fbdev_cma_hotplug_event() already checks for NULL pointers before
dereferencing, so callers don't need to do that.
