Solve the following python programming problem given the following code:
@ mock.patch ('ironic.objects.base.objects') 
def test_hook_keeps_newer_properly(self, mock_objects) : 
    reg = base.IronicObjectRegistry () 
    reg.registration_hook (MyObj, 0) 
    class MyOlderObj (object) : 
        VERSION = '1.1' 
        @ classmethod 
        def obj_name(cls) : 
            return 'MyObj' 
self.assertEqual (MyObj, mock_objects.MyObj) 
    reg.registration_hook (MyOlderObj, 0) 
    self.assertEqual (MyObj, reg.MyObj) 

    
    

    Fix the buggy line: self.assertEqual (MyObj, reg.MyObj)
assistant
#Here is Python code to fix the buggy line: self.

self.assertEqual (MyObj, mock_objects.MyObj)
