Subject[PATCH 09/25] media: hantro: do a PM resume earlier
Date
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().
