From 9a536b0cb8f83bd979fe274ef0197ece12a3ed09 Mon Sep 17 00:00:00 2001 From: Matthias Reichl Date: Thu, 20 Feb 2020 21:29:56 +0100 Subject: [PATCH] ASoC: pcm512x: Fix unbalanced regulator enable call in probe error path commit ac0a68997935c4acb92eaae5ad8982e0bb432d56 upstream. When we get a clock error during probe we have to call regulator_bulk_disable before bailing out, otherwise we trigger a warning in regulator_put. Fix this by using "goto err" like in the error cases above.
