mc13xxx_parse_regulators_dt() goes through dt tree to search for regulator
sub-nodes. For each matched node, later on it will be used and registered
into a regulator_dev.

of_node_get() should be called to increase its refcount.

I think it's done by regulator core:

commit 63c7c9e16c8e92cc069854f2babdf82d2d38e4c7
regulator: core: Get and put regulator of_node

Yes, that's the idea anyway.  It's possible this is buggy though.
