In the Linux kernel, the following vulnerability has been resolved:
net: dsa: lantiq_gswip: Fix refcount leak in gswip_gphy_fw_list
Every iteration of for_each_available_child_of_node() decrements
the reference count of the previous node.
when breaking early from a for_each_available_child_of_node() loop,
we need to explicitly call of_node_put() on the gphy_fw_np.
Add missing of_node_put() to avoid refcount leak.
