From: Allen-KH Cheng <[email protected]>
In SOF OF device, pm_runtime_put_autosuspend() is not
matching any pm_runtime_get_sync().
This is imbalanced for PM runtime.
Also, for consistency we call pm_runtime_mark_last_busy()
before enabling PM runtime.
1. Remove pm_runtime_put_autosuspend() in probe_complete
2. Reorder PM runtime calls int probe_complete
