The mask is meant to cover the flags that can be overridden by the module parameter. The 'k' quirk character sets US_FL_NO_SAME, but US_FL_NO_SAME is not included in the mask. As a result, the module parameter can set US_FL_NO_SAME, but it cannot clear a built-in US_FL_NO_SAME flag by providing an override entry that omits 'k'. Add US_FL_NO_SAME to the mask so that the module parameter can override it in the same way as the other supported flags.
