Subject: pinctrl: nomadik: Fix refcount leak in nmk_pinctrl_dt_subnode_to_map
From: Miaoqian Lin <linmq006@xxxxxxxxx>
commit 4b32e054335ea0ce50967f63a7bfd4db058b14b9 upstream.
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."
