Subject: [PATCH] drm/bridge: nwl-dsi: Fix PM disable depth imbalance in nwl_dsi_probe
Date: Wed, 5 Jan 2022 10:48:26 +0000 [thread overview]
Message-ID: <20220105104826.1418-1-linmq006@gmail.com> (raw)
The pm_runtime_enable will increase power disable depth.
Thus a pairing decrement is needed on the error handling
path to keep it balanced according to context.
Fixes: 44cfc62 ("drm/bridge: Add NWL MIPI DSI host controller support")
