5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miaoqian Lin <linmq006@xxxxxxxxx>
[ Upstream commit c818ae563bf99457f02e8170aabd6b174f629f65 ]
of_find_node_by_phandle() returns a node pointer with refcount incremented,
We should use of_node_put() on it when not needed anymore.
Add missing of_node_put() to avoid refcount leak.
Fixes: d3e5116119bd ("pinctrl: add pinctrl driver for Rockchip SoCs")
