Subject: [PATCH 5.17 0478/1126] drm/bridge: lt9611: Fix an error handling path in lt9611_probe()

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 9987151a90567785beebcbd5c8ac58d05f254137 ]

If lt9611_audio_init() fails, some resources still need to be released
before returning an error code.

Add the missing goto the error handling path.
