Subject: [PATCH v3 7/9] drm: rcar-du: Skip disabled outputs
Date: Mon,  6 Mar 2017 02:03:00 +0200	[thread overview]
Message-ID: <20170306000302.14149-8-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <20170306000302.14149-1-laurent.pinchart+renesas@ideasonboard.com>

When a DT node connected to a DU output is disabled no bridge will ever
be instantiated for it. Skip the output in that case.
