[ Upstream commit 69306a947b3ae21e0d1cbfc9508f00fec86c7297 ]
pm_runtime_get_sync() will increase the runtime PM counter even it returns an error. Thus a pairing decrement is needed to prevent refcount leak. Fix this by replacing this API with pm_runtime_resume_and_get(), which will not change the runtime PM counter on error.
