This is a good find thanks. I think there's a small problem in the way the layering is done. I think ata_scsi_ioctl needs to be expanded to pass the port in all the time. That way other implementors don't have to remember to special case HDIO_GET_IDENTITY. When you redo this, ipr will need altering as well (rather than also having the identity exception added).
