The iseries driver wants to hang kobjects off of its driver, so, to
preserve backwards compatibility, we need to add a call to the driver
core to allow future changes to work properly.
Hopefully no one uses this function in the future and the iseries_veth
driver authors come to their senses so I can remove this hack...
