Subject: [PATCH v3 1/7] drm: sun4i: dsi: Use drm_of_find_panel_or_bridge
Date: Mon, 15 Feb 2021 01:10:56 +0530	[thread overview]
Message-ID: <20210214194102.126146-2-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20210214194102.126146-1-jagan@amarulasolutions.com>

Replace of_drm_find_panel with drm_of_find_panel_or_bridge
for finding panel, this indeed help to find the bridge if
bridge support added.

Added NULL in bridge argument, same will replace with bridge
parameter once bridge supported.
