Subject: [PATCH] ASoC: img-spdif-in: Fix runtime PM imbalance on error
Git-commit: 53865b3259554389e40aeead392151c819b52a71
Patch-mainline: v5.8-rc1
References: jsc#SLE-16518
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.
