Solve the following python programming problem given the following code:
def __init__(self, fget, fset = None, fdel = None, expr = None) : 
    'Create a new :class:`.hybrid_property`.

        Usage is typically via decorator::

            from sqlalchemy.ext.hybrid import hybrid_property

            class SomeClass(object):
                @hybrid_property
                def value(self):
                    return self._value

                @value.setter
                def value(self, value):
                    self._value = value

        ' 
    self.fget = fget 
    self.fset = fset 
    self.fdel = fdel 
    self.expr = (expr or fget) 
    util.update_wrapper (fset, fget) 

    
    

    Fix the buggy line: util.update_wrapper (fset, fget)
