Bug description:
  ===SRU Justification===
  [Impact]
  UVC1.5 Realtek webcam on XPS 9370 does not work.

  [Test]
  Both the bug reporter and I can confirm the patch from Realtek works.

  [Fix]
  Use correct version control length for UVC1.5.

  [Regression Potential]
  Low. This only affects UVC1.5 webcams, which is quite rare in the wild.

  ===Original Bug Report===
  The webcam is detected by the system, but no applications detect it.
