Title:
  Failed to call EVIOCSKEYCODE with scan code 0xc022d, and key code 103:
  Invalid argument

Status in systemd package in Ubuntu:
  New

Bug description:
  I run an up-to-date Ubuntu 20.04.1 LTS "focal" with kernel
  5.4.0-42-generic on Dell Latitude E6440.  Upon examining the output of
  journalctl -b, I see this:

  Aug 03 19:22:15 pseudonymizedHostname systemd[1]: Condition check resulted in Show Plymouth Boot Screen being skipped.

  Aug 03 19:22:15 pseudonymizedHostname systemd-udevd[385]: event8: Failed to call EVIOCSKEYCODE with scan code 0xc022e, and key code 108: Invalid argument

  "Invalid argument" means that something goes wrong there, and I don't know what it is.
  On my laptop, event8 seems to be keyboard-related:

  $ sudo cat /proc/bus/input/devices | grep -C 5 event8

  The issue report
  https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1754921 is
  probably related but marked as a duplicate of a no longer existing
  issue report (#1750855).

  The report
  https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1597415
  describes a similar issue for older kernels; the differences pertain
  to error message, error code, input..., and, opposed to #19 there, I
  have no Windows partitions (except /boot/efi vfat) in /etc/fstab; mine
  is not a dual-boot machine.
