I despise ?: use just so much, EXCEPT for when it's used in something
like this:

Which really is the only valid way I'd put up with it :)

So can you rewrite the change above to be just:

	struct kobject *kobj_parent = NULL;

	...

	if (parent)
		kobj_parent = &parent->kobj;

Which is much simpler to read, right?
