I don't think this patch is useful for stable users. It corrects a
device tree layout issue. Any existing users of the functionality will
have an odd, but working device tree and that will continue working
(with a warning) after applying this patch. It just has a property on
the "wrong" node. I don't think I'd like to update my device tree in a
stable update.
If you apply it anyway, please also apply a fixup:
