Subject: [PATCH v4 21/24] drm/bridge: tc358775: Switch to devm MIPI-DSI helpers
Date: Fri, 10 Sep 2021 12:12:15 +0200 [thread overview]
Message-ID: <20210910101218.1632297-22-maxime@cerno.tech> (raw)
In-Reply-To: <20210910101218.1632297-1-maxime@cerno.tech>
Let's switch to the new devm MIPI-DSI function to register and attach
our secondary device. This also avoids leaking the device when we detach
the bridge.
