From: Markus Elfring Date: Sat, 16 Jul 2016 07:10:40 +0000 (+0200) Subject: drm/hdlcd: Delete an unnecessary check before drm_fbdev_cma_hotplug_event() X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=536cea6073381aa9ace9743cd94e77d80018e3ee;p=openwrt%2Fstaging%2Fblogic.git drm/hdlcd: Delete an unnecessary check before drm_fbdev_cma_hotplug_event() 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.
