Yeah that's why:

+       sector_size = ata_id_logical_sector_size(args->id);

Where the logical sector size of the device is reported with the same
function in ata_scsi_dev_config() and ata_scsiop_read_cap().

So were you trying to pointing out something I am still missing, or
were you merely confirming I was right?
