Ok for Xenial (v4.4) kernel, there's one missing commit that adds UVC1.5
to device ID.
The commit for this bug is still needed though.
I'll send another SRU to backport the commit.

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.
