Another comment suggested adding
of_node_put(out_args.np <http://out_args.np>);
here.
is it really? most of the driver that call this function don't call of_node_put. but it seems harmless to call of_node_put.
Even if everyone else is doing things wrong, that doesn't mean
that you should do the same, nor is it a good idea to use it
as argument.
