stable inclusion from stable-v5.10.150 commit 70f0a0a27d79f689defc5f5f0bd47d07813e6dea category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0XA

--------------------------------
[ Upstream commit 4e343bafe03ff68a62f48f8235cf98f2c685468b ]
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.
