[Bug 1597415] Re: systemd-udevd: Error calling EVIOCSKEYCODE on device node '/dev/input/event9' (scan code 0x150, key code 190): Invalid argument

[Michael Doube]

Fix may be dependent on kernel version; testing with stock kernel for
Ubuntu 16.04, v4.4, results in:

Jan 10 19:32:33 Bethany systemd-udevd[332]: Error calling EVIOCSKEYCODE
on device node '/dev/input/event11' (scan code 0x100150, key code 190):
Invalid argument

Previous testing used kernel v4.9 from here: http://kernel.ubuntu.com
/~kernel-ppa/mainline/?C=N;O=D
