[PATCH 10/10] powerpc: Add uevent handler for ibmebus
From: Sylvain Munaut <hidden>

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.
