Subject: [PATCH v7 03/23] drm/connector: Only register TV mode property if present
Date: Mon, 07 Nov 2022 15:16:29 +0100 [thread overview]
Message-ID: <20220728-rpi-analog-tv-properties-v7-3-7072a478c6b3@cerno.tech> (raw)
In-Reply-To: <20220728-rpi-analog-tv-properties-v7-0-7072a478c6b3@cerno.tech>
The drm_create_tv_properties() will create the TV mode property
unconditionally.
However, since we'll gradually phase it out, let's register it only if we
have a list passed as an argument. This will make the transition easier.
