Subject: [PATCH 4/4] drm: Clean up drm_dev_unplug
Date: Wed,  2 Aug 2017 13:56:04 +0200	[thread overview]
Message-ID: <20170802115604.12734-5-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20170802115604.12734-1-daniel.vetter@ffwll.ch>

Use drm_dev_unregister to unregister the interfaces, which also allows
us to simplify the open_count == 0 case.
