The ready_to_power_off flag is used to give indication to ATA layer if this device's power can be removed when runtime suspended. This flag is determined by individual SCSI driver like sr, sd. This flag is introduced to support zero power ODD. When ODD is runtime suspended, it may not be OK to remove its power. But for disk, it is always OK to be powered off, so set this flag.
