In the Linux kernel, the following vulnerability has been resolved:

mtd: partitions: Fix refcount leak in parse_redboot_of

of_get_child_by_name() 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.
