Summary
In the Linux kernel, the following vulnerability has been resolved:
net: altera: Fix refcount leak in altera_tse_mdio_create
Every iteration of for_each_child_of_node() decrements
the reference count of the previous node.
When break from a for_each_child_of_node() loop,
we need to explicitly call of_node_put() on the child node when
not need anymore.
Add missing of_node_put() to avoid refcount leak.
