- struct ata_device * ata_scsi_find_dev(struct ata_port * ap, const struct scsi_device * scsidev);
- ATA port to which the device is attached
- SCSI device from which we derive the ATA device
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.
Associated ATA device, or NULL if not found.
