Yes, but, what is this file doing mucking around in a "private" variable
to the driver core? No wonder I never caught this, as it's one
reference away from being declared static.
Please fix this file up properly, like the comment in vio.c shows:
* XXX once vio_bus_type.devices is actually used as a kset in
* drivers/base/bus.c, this function should be removed in favor of
* "device_find(kobj_name, &vio_bus_type)"
The fact that this function works at all is so tenous and scary that I
would never trust it on a running system. Let alone something so
"enterprise" as a pseries box...
thanks,
