From: Qiushi Wu <wu000273@umn.edu> [ Upstream commit 63e36a381d92a9cded97e90d481ee22566557dd1 ] 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.
