CVE-2022-49351

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.
