2017-03-06uvc-gadget: Do not send Set Interface (alternate setting) response twiceRoger Quadros
On alternate setting change, the webcam gadget sends us a UVC_EVENT_STREAMON or UVC_EVENT_STREAMOFF event. In the first case, the driver will issue a delayed status response automatically when we call the VIDIOC_STREAMON ioctl. In the second case, the driver sends the status response immediately. We must thus not send the status response manually with UVCIOC_SEND_RESPONSE in any of those cases. Without this, the ISO streaming doesn't work if host application (e.g. luvcview) is closed and restarted. On dwc3 gadget controller it was resulting in Buffer Expiry error on the ISO endpoint.
