With runtime PM, the devices get suspended while the system is up and running in order to save power. At such times, it is important to re-evaluate the required performance state of the domain, in order to choose a lower state if possible.
This patch updates the genpd suspend/resume callbacks to do that.

Doesn't this assume that a device in the domain would need to change performance state while runtime suspended. How would that happen?
Rather than adding this here, I would think that drivers would instead remove any QoS requests before going into runtime suspend, which would trigger an update before runtime suspending.
