Subject: [PATCH 4.14 086/242] ASoC: wm8998: Fix PM disable depth imbalance on error

From: Zhang Qilong <zhangqilong3@...wei.com>

[ 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.
