[PATCH] ASoC: img-spdif-in: Fix runtime PM imbalance on error

From: Dinghao Liu
Date: Wed May 27 2020 - 04:44:19 EST


pm_runtime_get_sync() increments the runtime PM usage counter even
the call returns an error code. Thus a pairing decrement is needed
on the error handling path to keep the counter balanced.
