void eeh_add_device_early (struct device_node * dn);
This routine must be used to perform EEH initialization for PCI devices that were added after system boot (e.g. hotplug, dlpar). This routine must be called before any i/o is performed to the adapter (inluding any config-space i/o). Whether this actually enables EEH or not for this device depends on the CEC architecture, type of the device, on earlier boot command-line arguments & etc.
