Subject: [patch 12/33] PS3: System-bus uevent

From: Geoff Levand <[email-masked]>
Date: Fri, 15 Jun 2007 14:55:14 -0700

From: David Woodhouse <[email-masked]>

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.
