Subject: [PATCH v3 09/10] drm/atmel-hlcdc: Remove unnecessary NULL check
Date: Tue, 21 Mar 2017 09:13:57 +0100	[thread overview]
Message-ID: <20170321081358.27237-10-thierry.reding@gmail.com> (raw)
In-Reply-To: <20170321081358.27237-1-thierry.reding@gmail.com>

From: Thierry Reding <treding@nvidia.com>

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