Subject: [PATCH] pinctrl/rockchip: Add missing of_node_put() in rockchip_pinctrl_probe
Date: Mon,  7 Mar 2022 12:02:34 +0000	[thread overview]
Message-ID: <20220307120234.28657-1-linmq006@gmail.com> (raw)

The device_node pointer is returned by of_parse_phandle()  with refcount
incremented. We should use of_node_put() on it when done.

Fixes: 1e747e59cc4d ("pinctrl: rockchip: base regmap supplied by a syscon")
Fixes: 14dee8677e19 ("pinctrl: rockchip: let pmu registers be supplied by a syscon")
