Solve the following python programming problem given the following code:
def deauthorize_node(self) : 
    addon_short_name = self.addon_short_name 
    Provider = self.Provider 
    @ must_not_be_registration 
    @ must_have_addon (addon_short_name, 'node') 
    @ must_have_permission ('write') 
    def _deauthorize_node(auth, node_addon, **kwargs) : 
        ' Removes addon authorization from node.
            ' 
        provider = Provider () 
        return provider.remove_user_auth (node_addon, auth.user) 
_deauthorize_node.__name__ = '{0}_deauthorize_node'.format (self) 
    return _deauthorize_node 

    
    

    Fix the buggy line: _deauthorize_node.__name__ = '{0}_deauthorize_node'.format (self)

#Here is Python code to fix the buggy line: _deauthorize_node.

_deauthorize_node.__name__ = '{0}_deauthorize_node'.format (addon_short_name)
