Summary
In the Linux kernel, the following vulnerability has been resolved: mtd: maps: Fix refcount leak in ap_flash_init 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.
