co where this return value is needed. For pnp_stop_dev() the same check
(pnp_can_disable()) is performed in the suspend routine to avoid that
particular problem. For resume my assumption was that a device that
doesn't support activation will not have a driver attached to it.
Perhaps this is wrong?
i8042 registers drivers for keyboard and AUX ports to gather
information whether the ports are present and what IRQ and IO ports
shoudl be used to access them. And I have seen a few boxes that do not
alloe [de]activate these devices.
