      [media] [1/2,ver,1.89] DM04/QQBOX Interupt Urb and Timing changes · 95c21c41
      tvboxspy authored
      Reduce buffer size of Interupt urb to 128 bytes and polling
      interval to 8.
      
      The devices buffer appears to only handle a maxium of 40 bytes.
      If the buffer is full a slowing effect is noticed causing occasionnal
      dropped streaming packets.

      For uvc device, dev->vdev.dev is the &intf->dev,
      uvc_delete code is as below:
      	usb_put_intf(dev->intf);
      	usb_put_dev(dev->udev);
      
      	uvc_status_cleanup(dev);
      	uvc_ctrl_cleanup_device(dev);
      
      	if (dev->vdev.dev)
      		v4l2_device_unregister(&dev->vdev);
      
      Fix it by get_device in v4l2_device_register and put_device in v4l2_device_disconnect
