Prior to this patch, cmd_exec_dev_diagnostic relied upon ide_set_signature to clear the device register. While the preservation of the drive bit by ide_set_signature is necessary for the DEVICE RESET, IDENTIFY DEVICE, and READ SECTOR commands, ATA/ATAPI-6 specifies that "DEV shall be cleared to zero" for EXECUTE DEVICE DIAGNOSTIC. This deviation was uncovered by the ATACT Device Testing Program written by Hale Landis.
