Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: bgmac: Fix refcount leak in bcma_mdio_mii_register
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.
