That's not why CPUFREQ_ASYNC_NOTIFICATION is used. It is used only for the cases
where the target()/target_index() callback defers the work to some other entity
(like a workqueue) and it is not guaranteed that the frequency will be changed
before these helpers return.
I don't think your patch is required.
