    Subject[PATCH v2 06/14] sg_io: whitelist another command for multimedia devices
    Date
    Three MMC commands were never included: PLAY AUDIO(12), SERVICE ACTION
    IN(12), MECHANISM STATUS. Add MECHANISM STATUS, the only one that has
    not been obsoleted in recent versions of the standard.
