From: Miaoqian Lin <linmq006@gmail.com> stable inclusion from stable-v5.10.150 commit c01bfd23cc13a420b3f6a36bcab98410f49d480d category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0XA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit db16a80c76ea395766913082b1e3f939dde29b2c ] of_find_matching_node() 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.
