Bug description:
  Upgrade focal fwupd from 1.3.11 to 1.4.7.

  [Impact]

   * touchscreen is working after login on certain HW
   * Current LTS is the OEM Project scope, so we need to SRU it.
   * It's a specific HW-related upstream fix.

  [Test Plan]

   * Wit this upgraded, with specific HW, check if touchscreen still
     working after login.

  [Where problems could occur]
  [Other Info]

   * It's low risk given it's an HWE upstream fix.

  Hello,

  I have freshly installed Ubuntu 20.04 and have a bug on my M3800.
  The touchscreen is working good on login screen bug after I enter my credentials and the gnome session open I can't use it.

  I'm on a dual boot computer and all is working well on Windows 10.

  How can I help you to track this bug and solve it ?

  Best regards
