proto_tree_get_parent()

[Eloy Paris <peloy () chapus net>]

Is this right (from epan/proto.c):

proto_item*
proto_tree_get_parent(proto_tree *tree) {
        if (!tree)
                return (NULL);
        return (proto_item*) tree;
}

This basically returns the same thing that is received as a parameter. 
Shouldn't tree->parent be returned instead, just as 
proto_item_get_parent() (a few lines above in the same file) does?

The weird thing is that there is code using this seemingly broken 
proto_tree_get_parent(). I don't know how things are working given that 
proto_tree_get_parent() is not really providing the parent node.

Confused,
