PHP5.3 - Deprecated function: Call-time pass-by-reference has been deprecated in drupal_load()

Nagging message due to copy-and-past mistake:

 function wf_field_property_get($entity, array $options, $name, $entity_type, &$context) {
   module_load_include('inc', 'wf_field', 'includes/wf_field_property.wrapper');
   // @todo clarify
-  return new WfFieldPropertyWrapper($entity, $options, $name, $entity_type, &$context);
+  return new WfFieldPropertyWrapper($entity, $options, $name, $entity_type, $context);
 }
