The only new thing this patch would break is autosuspend for the type_1
chip.  Suspend for the chip was already broken.  Oliver and Alan 
suggested adding a reset resume quirk for this chip, so I need to try
that
before this patch is applied.

If a reset resume doesn't help, the driver could refuse to autosuspend
the type_1 chip.  But what about refusing during system suspend or
hibernate?
Should a system suspend be stopped because one device can't handle
suspend?
