[PATCH] Driver core: add proper symlinks for devices
We need to create the "compatible" symlinks that class_devices used to create when they were in the class directories so that userspace does not know anything changed at all. Yeah, we have a lot of symlinks now, but we should be able to get rid of them in a year or two... (wishful thinking...) Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
