Is this some kind of mis-merge?

In sas_discover.c:

	case SAS_SATA_DEV:
	case SAS_SATA_PM:
#ifdef CONFIG_SCSI_SAS_ATA
		error = sas_discover_sata(dev);
		break;
#else
		pr_notice("ATA device seen but CONFIG_SCSI_SAS_ATA=N so cannot attach\n");
		fallthrough;
#endif
		fallthrough;	/* only for the #else condition above */
