In the last year, HP mentions HP machines need to use hp-wireless (HPQ6001) as the rfkill source[1].
However, HP confirms the HPQ6001 has been retired in the platforms since 2022.
In the platforms after 2022, there are two sources of rkfill events (intel-hid, atkbd) and HP only guarantee the intel-hid works.
Therefore, the upstream already accept the patch[2] to unmask intel-hid and mention this big change in the NEWS.
This change makes the pre-2022 HP platforms meet the regression since they have two rfkill events (HPQ6001 and intel-hid) be triggered if pressing function key.
Thus, there is a patch[3] to make sure the GNOME could deal with this case smoothly.
However, the systemd change will still cause other DEs meet the regression (xfce, KDE, lxde, etc..).
Backport systemd change to make HP 2022 platforms work is not the best choice on stable version (focal in this case).
We still need a solution to make airplane key works on 2022 HP platforms (intel-hid and atkbd only).
The potential solution from my mind that is to maintain a whitelist to unmask intel-hid in ubuntu-patch in focal, something like:
```
evdev:name:Intel HID events:
KEYBOARD_
```
after "KEYBOARD_
