Solve the following python programming problem given the following code:
def iterDescendantsWithName(dom, tagName, max_depth = 0) : 
    '    Iterate over descendant elements whose name is contained in
    tagName (or is named tagName if tagName is a string).  Only
    consider nodes up to max_depth deep when max_depth is greater than
    zero.
    ' 
    if isinstance (tagName, basestring) : 
        tagName = (tagName,) 
def match(d) : 
        return (d.tagName in tagName) 
return iterMatchingDescendants (dom, dom, max_depth) 

    
    

    Fix the buggy line: return iterMatchingDescendants (dom, dom, max_depth)
