[patch 12/30] PS3: System-bus uevent
From: Geoff Levand <hidden>
Date: 2007-06-12 18:55:36
From: David Woodhouse <dwmw2@infradead.org> 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.
