That was probably me, but in a different context. ;-)
Use 'bool' for functions that are intended as boolean, eg.
'system_entering_hibernation()' will return 'true' if the system is entering
hibernation at the moment and 'false' otherwise, but for functions like
pci_handle_one_wakeup_event() the standard it to return 0 on success, so IMO
we should follow the standard.
