From: Miaoqian Lin <linmq006@gmail.com> stable inclusion from stable-v5.10.134 commit 493ceca3271316e74639c89ff8ac35883de64256 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5ZVR7 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 80192eff64eee9b3bc0594a47381937b94b9d65a ] of_find_matching_node_and_match() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.
