Summary
In the Linux kernel, the following vulnerability has been resolved: pinctrl: nomadik: Fix refcount leak in nmk_pinctrl_dt_subnode_to_map of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak."
