The DCVDD one needs an of_node_put but I am not sure this one
does. As it will be copied into the regulator device of_node by
the regulator core so wont of_node_put be called when the device
is destroyed? Admittedly I haven't checked that but seems
sensible that the device structure would put its of_node when it
closes down.

Thanks,
