Subject: [PATCH 3/5] drm/imx: don't destroy mode objects manually on driver unbind
Date: Thu, 11 Aug 2016 11:18:49 +0200	[thread overview]
Message-ID: <1470907131-2726-3-git-send-email-l.stach@pengutronix.de> (raw)
In-Reply-To: <1470907131-2726-1-git-send-email-l.stach@pengutronix.de>

Instead let drm_mode_config_cleanup() do the work when taking down
the master device. This requires all cleanup functions to be
properly hooked up to the mode object .destroy callback.
