Wakeup GPE hasn't a handler. If system is waked up by such GPE like a USB hotplug, I saw a lot of error reporting the GPE hasn't handler. acpi_leave_sleep_state will clear the GPE but it's too late, we should doe it before interrupt is re-enabled. Maybe we should just clear wakeup GPE here, but clear all GPEs sounds not harmful in my test. Not sure other systems.
