+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.
