From ddc4a7296f3abd28a902f38ae915224d6d93edca Mon Sep 17 00:00:00 2001

Subject: [PATCH] [PATCH] powerpc: Add uevent handler for ibmebus
Adding this handler allow userspace to properly handle the module
autoloading. The generation of the uevent itself is now common to
all bus using of_device, so not much code here.
But we still need a small wrapper to filter out the dummy root
device node used by this bus.
