Subject: [PATCH 06/14] drm/bridge: analogix_dp: remove clk handling from analogix_dp_set_bridge
Date: Fri, 3 May 2024 17:11:21 +0200 [thread overview]
Message-ID: <20240503151129.3901815-7-l.stach@pengutronix.de> (raw)
In-Reply-To: <20240503151129.3901815-1-l.stach@pengutronix.de>
The clock is already managed by runtime PM, which is properly invoked
from the analogix_dp_set_bridge function, so there is no need for an
additional reference.
