Please omit this header when sending patches.
We found this type(0c45:6437) of Microdia camera does not work(no stream packets sent out from camera any longer) after resume from sleep, but unbind/bind driver will work again.
So introduce the quirk of UVC_QUIRK_FIX_SUSPEND_RESUME to fix the problem for this type of Microdia camera.
