rpaphp_add_slot – declare a hotplug slot to the hotplug subsystem. : device node of slot

This subroutine will register a hotplugable slot with the PCI hotplug infrastructure. This routine is typically called during boot time, if the hotplug slots are present at boot time, or is called later, by the dlpar add code, if the slot is being dynamically added during runtime.

If the device node points at an embedded (built-in) slot, this routine will just return without doing anything, since embedded slots cannot be hotplugged.

To remove a slot, it suffices to call rpaphp_deregister_slot().
