Subject: [PATCH 07/27] drm: bridge: simple-bridge: Make connector creation optional
Date: Tue, 26 May 2020 04:14:45 +0300	[thread overview]
Message-ID: <20200526011505.31884-8-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <20200526011505.31884-1-laurent.pinchart+renesas@ideasonboard.com>

Make the connector creation optional to enable usage of the
simple-bridge with the DRM bridge connector helper.
