Solve the following python programming problem given the following code:
def is_device_report(doc) : 
    'exclude device reports' 
    device_report_xmlns = 'http://code.javarosa.org/devicereport' 
    def _from_form_dict(doc) : 
        return (isinstance (doc, dict) and ('@xmlns' in doc) and (doc ['@xmlns'] == device_report_xmlns)) 
def _from_xform_instance(doc) : 
        return (getattr (doc, 'xmlns', None) == device_report_xmlns) 
return (_from_form_dict (doc) or _from_xform_instance (_from_form_dict)) 

    
    

    Fix the buggy line: return (_from_form_dict (doc) or _from_xform_instance (_from_form_dict))
