From 0615a444c5dd955db6cc7bd96292a21d40bf321c Mon Sep 17 00:00:00 2001 From: Miaoqian Lin Date: Mon, 7 Mar 2022 12:02:34 +0000 Subject: [PATCH] pinctrl/rockchip: Add missing of_node_put() in rockchip_pinctrl_probe [ Upstream commit 89388f8730699c259f8090ec435fb43569efe4ac ] The device_node pointer is returned by of_parse_phandle() with refcount incremented. We should use of_node_put() on it when done.
