Subject: [PATCH 19/27] drm: bridge: dw-hdmi: Split connector creation to a separate function
Date: Tue, 26 May 2020 04:14:57 +0300 [thread overview]
Message-ID: <20200526011505.31884-20-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <20200526011505.31884-1-laurent.pinchart+renesas@ideasonboard.com>
Isolate all the code related to connector creation to a new
dw_hdmi_connector_create() function, to prepare for making connector
creation optional.
