[Cbe-oss-dev] [PATCH] uevent support for ps3_system_bus

[David Woodhouse]

To allow userspace to automatically load modules, we need to hook up
uevent for ps3_system_bus devices. I've used the form 'ps3:%d' with the
ps3_match_id, since that's what we use for matching drivers. Is there
any point in adding the bus_id and dev_id too?
