Gah, kbuild robot even told me about this typo and I missed it. Please
let me know if you can fix up or if I should resend (or drop). I'd
rather it not get dropped as I want to convert of_find_node_by_name() to
stop dropping reference to the starting node, as half of the users do
not expect it.

Thanks.
