Bug description:
  After upgrading to kmod (24-1ubuntu3.1) the trackpads stop working on
  Lenovo 11e 2nd gen machines.

  We have a fleet of approximetly 1000 of them in production running
  ubuntu 18.04. Prior to this update the trackpads worked out of box in
  18.04.

  We are currently working around the issue by deploying our own
  blacklist files.
