Directly related to T431.
Librem 13 v2, v3 **US model** devices have a wrong mapping of the pipe key. We introduced a workaround in PureOS and forwarded it upstream. However, the workaround also affects **UK and DE models** which do not have this problem! The result is that the pipe key on these models is now acting like the # key.
Removing the lines from `/usr/lib/udev/hwdb.d/60-keyboard.hwdb`:
```
# Purism Librem 13 V2
evdev:atkbd:dmi:bvn*:bvr*:bd*:svnPurism*:pn*Librem13v2*:pvr*
KEYBOARD_KEY_56=backslash
# Purism Librem 13 V3
evdev:atkbd:dmi:bvn*:bvr*:bd*:svnPurism*:pn*Librem13v3*:pvr*
KEYBOARD_KEY_56=backslash
```
__enables correct functioning__ of the pipe key again on **UK** and **DE** models.
I suggest removing the workaround from our systemd as well as removing it from upstream, as it only introduces whole bunch of other issues, and have the hardware manufacturer deal with the bug at the //keyboard EC firmware// level themselves.
