USB: gadget: composite device-level suspend/resume hooks
Address one open question in the composite gadget framework:
Yes, we should have device-level suspend/resume callbacks
in addition to the function-level ones. We have at least one
scenario (with gadget zero in OTG test mode) that's awkward
to handle without it.
