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.
|
