I personally think all these __free() are ugly and magical. Can it
somehow be made part of of_get_child_by_name()? Add an
of_get_child_by_name_func_ref() which holds a reference to the node
for the scope of the function?

for_each_available_child_of_node_scoped() is fine. Once you have fixed
all the reverse christmas tree, please submit them. But i would like
to see alternatives to __free(), once which are less ugly.
