[PATCH] INPUT: Create symlinks for backwards compatibility
This creates symlinks in /sys/class/input/ to the nested class devices to help userspace cope with the nesting. Unfortunatly udev still needs to be updated as it can't handle symlinks properly here :( Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
