[PATCH 5.4 122/453] ASoC: wm8998: Fix PM disable depth imbalance on error

From: Greg Kroah-Hartman
Date: Mon Dec 28 2020 - 08:44:24 EST


From: Zhang Qilong <zhangqilong3@xxxxxxxxxx>

[ Upstream commit 193aa0a043645220d2a2f783ba06ae13d4601078 ]

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.
