Subject: [PATCH v5 14/21] drm/bridge: sn65dsi83: Switch to devm MIPI-DSI helpers
Date: Thu, 21 Oct 2021 09:39:40 +0200 [thread overview]
Message-ID: <20211021073947.499373-15-maxime@cerno.tech> (raw)
In-Reply-To: <20211021073947.499373-1-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 but don't remove its driver.
Acked-by: Sam Ravnborg <sam@ravnborg.org>
