Bug description:
  [Impact]
  Touchpad on a ByteSpeed C15B laptop is not working.
  User will need to add i8042.noloop=1 to boot options to make it work.

  [Fix]
  * a48491c65b513e ("Input: i8042 - add ByteSpeed touchpad to noloop table")

  This fix can be cherry-picked into all affected releases.

  [Test Case]
  Test kernel for Bionic / Focal can be found here:
  https://people.canonical.com/~phlin/kernel/lp-1906128-C15B/

  And they have been tested with positive test results.

  [Where problems could occur]
  The fix is just a small and simple hardware quirk. I can't think of any potential problem for now.

  == Original Bug Report ==
  Touchpad hardware is OK and works for Win10.  Not working for live disc, not for 18.04 and not for 20.04 after upgrading.  I've attached a Logitech wireless mouse with its USB adapter and that works.   Bluetooth is also missing, but I have not started trying to skull that out.  I'm happy to help try debugging things, and to help resolve the issue.
