Subject: [PATCH 2/3] drm/bridge/synopsys: dsi: extend the prototype of mode_valid()
Date:   Sat, 18 Dec 2021 22:50:53 +0100
Message-ID: <20211218215055.212421-2-antonio.borneo@foss.st.com>

To evaluate the validity of a video mode, some additional internal
value has to be passed to the platform implementation.

Extend the prototype of mode_valid().
