Description

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

ARM: cns3xxx: Fix refcount leak in cns3xxx_init

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.
