Subject: [PATCH v2 3/3] pinctrl: th1520: Convert dt child node loop to
scoped iterator
Convert th1520_pinctrl_dt_node_to_map() to use a scoped iterator with
for_each_available_child_of_node_scoped(). As a result, there is no need
to call of_node_put() anymore. The put_child label has been renamed to
free_map which is now a more accurate description.
