Subject: [PATCH] uvcvideo: add fix suspend/resume quirk for Microdia camera

   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.

   You didn't sign off.

   The preferred style is:
