Subject: [PATCH 5.17 234/772] drm/bridge: adv7511: clean up CEC adapter when probe fails

From: Lucas Stach <l.stach@...gutronix.de>

[ Upstream commit 7ed2b0dabf7a22874cb30f8878df239ef638eb53 ]

When the probe routine fails we also need to clean up the
CEC adapter registered in adv7511_cec_init().
