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.
