Subject: [PATCH] mtd: maps: Fix refcount leak in ap_flash_init
Git-commit: 77087a04c8fd554134bddcb8a9ff87b21f357926
Patch-mainline: v6.0-rc1
References: git-fixes
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.
Fixes: b0afd44bc192 ("mtd: physmap_of: add a hook for Versatile write protection")
