From: Qiushi Wu <[email protected]> [ Upstream commit 6b9fbb073636906eee9fe4d4c05a4f445b9e2a23 ]
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.
