stable inclusion from stable-v5.10.130 commit 3d90607e7e6afa89768b0aaa915b58bd2b849276 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5YRJO

--------------------------------
[ Upstream commit 34d2cd3fccced12b958b8848e3eff0ee4296764c ]
of_find_compatible_node() 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.
