[ Upstream commit 892bb6ecead9b834ba7ad1d07513e9eba1baa3a4 ]
The device_run() first enables the clock and then tries to resume PM runtime, checking for errors.
Well, if for some reason the pm_runtime can not resume, it would be better to detect it beforehand.
So, change the order inside device_run().
