Subject: [PATCH] ASoC: img: Fix a reference count leak in img_i2s_in_set_fmt
Git-commit: c4c59b95b7f7d4cef5071b151be2dadb33f3287b
Patch-mainline: v5.9-rc1
References: jsc#SLE-16518
pm_runtime_get_sync() increments the runtime PM usage counter even
when it returns an error code, causing incorrect ref count if
pm_runtime_put_noidle() is not called in error handling paths.
Thus call pm_runtime_put_noidle() if pm_runtime_get_sync() fails.
