[Impact]
There is no support of new F9 hotkey on Thinkpad X9 series:
    - [ 0, 0, 1, 240, 1] # EV_KEY / KEY_UNKNOWN 1

[Fix]
Lenovo Thinkpad 'X9-14 Gen 1' and 'X9-15 Gen 1' has new shortcut on F9 key
and send a new 0x131b hkey event when F9 key is pressed.

[Test]
Test on the Thinkpad X9:
$ sudo libinput record
select the number of "ThinkPad Extra Buttons".
Press F9 key, it shows:
    - [ 0, 0, 5, 9, 0] # EV_SW / SW_CAMERA_LENS_COVER 0

[Where problems could occur]
It make break Intel thinkpad acpi specific event.

They are Intel LNL which is supported from oem-6.11 which is EOL,
so SRU for 6.14+ kernel versions.
