The ready_to_power_off flag is used to give indication to ATA layer if this device's power can be removed after runtime suspended from the perspective of scsi driver. It is introduced to support zero power ODD. When ODD is runtime suspended, it may not be OK to remove its power. But for disk, there doesn't exist a scenario that when the disk is runtime suspended, it can't be powered off.
