Description

In the Linux kernel, the following vulnerability has been resolved: pinctrl: rockchip: Fix refcount leak in rockchip_pinctrl_parse_groups 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.
