kobject: add kobject_init_and_add function
Also add a kobject_init_and_add function which bundles up what a lot of the current callers want to do all at once, and it properly handles the memory usages, unlike kobject_register(); Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
