Title
net: dsa: mv88e6xxx: Fix refcount leak in mv88e6xxx_mdios_register
Summary
In the Linux kernel, the following vulnerability has been resolved: net: dsa: mv88e6xxx: Fix refcount leak in mv88e6xxx_mdios_register of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. mv88e6xxx_mdio_register() pass the device node to of_mdiobus_register(). We don't need the device node after it. Add missing of_node_put() to avoid refcount leak.
