The corresponding FROZEN hotplug notifier transitions used on
suspend/resume are ignored. Therefore the switch case action argument
is masked with the frozen hotplug notifier transition mask.

This seems sane, and I don't object, but can you tell us how this was 
tested?

Thanks,

It is compile tested only due to lack of hardware.
