save_state is a nonsense, didn't we kill it ? queue quiescing must beIsn't sysfs supposed to take care of this for us? IOW, I shouldn't have to call up to the SCSI midlayer from pcidev->suspend in order to notify it of a suspend, the midlayer should call the driver before we ever try to suspend. This may become important some day when the upper layers need to decide which order to bring pci devices down
done by the upper level, which is a bit nasty with things like md &
multipath... basically, the low level driver must have a way to notify
it's functional parent (as opposed to it's bus parent) that it's going
to sleep, and any path using this low level driver must then be
quiesced, the parent must resume only when all the drivers it relies
on are back up.
