From: Zhang Shurong <zhang_shurong@xxxxxxxxxxx> [ Upstream commit 0618c077a8c20e8c81e367988f70f7e32bb5a717 ] The pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced according to context. We fix it by calling pm_runtime_disable when error returns.
