From a508e33956b538e034ed5df619a73ec7c15bda72 Mon Sep 17 00:00:00 2001 From: Miaoqian Lin linmq006@gmail.com Date: Thu, 12 May 2022 08:44:45 +0400 Subject: [PATCH] ipmi:ipmb: Fix refcount leak in ipmi_ipmb_probe

of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak.
