I think that you're leaking ports_node,

/**
 * of_find_node_by_name - Find a node by its "name" property
 * @from:	The node to start searching from or NULL; the node
 *		you pass will not be searched, only the next one
 *		will. Typically, you pass what the previous call
 *		returned. of_node_put() will be called on @from.
 * @name:	The name string to match against
 *
 * Return: A node pointer with refcount incremented, use
 * of_node_put() on it when done.
