That's what I started with, but they really behave in a different way. And
there is no usage count. It's really best to just get rid of the custom PM
calls in favor of generic calls. That's because then we have much better
control for future changes in the driver with pm_runtime_use_autosuspend()
and pm_runtime_put_sync() for example.
