NAME
       ata_scsi_find_dev - lookup ata_device from scsi_cmnd

SYNOPSIS
       struct ata_device * ata_scsi_find_dev(struct ata_port * ap,
                                             const struct scsi_device * scsidev);

ARGUMENTS
       ap
           ATA port to which the device is attached

       scsidev
           SCSI device from which we derive the ATA device

DESCRIPTION
       Given various information provided in struct scsi_cmnd, map that onto an ATA bus, and
       using that mapping determine which ata_device is associated with the SCSI command to be
       sent.
