[PATCH 4.9 21/29] ARM: Fix refcount leak in axxia_boot_secondary

From: Miaoqian Lin <linmq006@gmail.com>

commit 7c7ff68daa93d8c4cdea482da4f2429c0398fcde upstream.

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.
