Subject: [PATCH v4 1/8] drm/vc4: hdmi: Constify drm_display_mode
Date: Mon, 29 Aug 2022 15:47:24 +0200 [thread overview]
Message-ID: <20220829134731.213478-2-maxime@cerno.tech> (raw)
In-Reply-To: <20220829134731.213478-1-maxime@cerno.tech>
We don't modify the drm_display_mode pointer we have in the driver in
most places, so let's make them const.
