NAME
       ata_scsi_translate - Translate then issue SCSI command to ATA device

SYNOPSIS
       int ata_scsi_translate(struct ata_device * dev, struct scsi_cmnd * cmd,
                              ata_xlat_func_t xlat_func);

ARGUMENTS
       dev
           ATA device to which the command is addressed

       cmd
           SCSI command to execute

       xlat_func
           Actor which translates cmd to an ATA taskfile

DESCRIPTION
       Our ->queuecommand function has decided that the SCSI command issued can be directly
       translated into an ATA command, rather than handled internally.

       This function sets up an ata_queued_cmd structure for the SCSI command, and sends that
       ata_queued_cmd to the hardware.

       The xlat_func argument (actor) returns 0 if ready to execute ATA command, else 1 to finish
       translation. If 1 is returned then cmd->result (and possibly cmd->sense_buffer) are
       assumed to be set reflecting an error condition or clean (early) termination.

       LOCKING: spin_lock_irqsave(host lock)

RETURN
       0 on success, SCSI_ML_QUEUE_DEVICE_BUSY if the command needs to be deferred.
