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

mfd: max77620: Fix refcount leak in max77620_initialise_fps

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.
