Laptop hotkeys

This bug was filed at the request of Hans de Goede, he as been super helpful: 
https://gitlab.freedesktop.org/libinput/libinput/-/issues/822


I have a couple of hotkeys on my MSI Summit E16 Flip laptop that don't work. I
attached a picture with the keys in question.

Keys number in the picture:

1. This button doesn't work: mute/unmute the microfone;

2. This button works: enable/disable webcam. There's also a physical switch on
the side of the laptop that enables/disables the webcam and it also works;

3. This button doesn't work: changes between power modes on Windows using the
provided MSI app MSIControl Center Pro;

4. This button doesn't work: rotate the screen 45º/90ª/180ª.



I also booted with wmi.debug_dump_wdg=1 and wmi.debug_event=1 on the kernel
commandline to check if there was any events.
I did the sudo evtest test and the hotkeys in question registered. I selected
number 3 in the list (see evtest.txt).

These are the events of the hotkeys in question:

Hotkey number 1 Microphone:

Event: time 1671569327.276408, type 4 (EV_MSC), code 4 (MSC_SCAN), value f1
Event: time 1671569327.276408, -------------- SYN_REPORT ------------
Event: time 1671569327.349220, type 4 (EV_MSC), code 4 (MSC_SCAN), value f1

Hotkey number 2 Camera:

Event: time 1671569327.656812, type 4 (EV_MSC), code 4 (MSC_SCAN), value ee
Event: time 1671569327.656812, type 1 (EV_KEY), code 212 (KEY_CAMERA), value 1
Event: time 1671569327.656812, -------------- SYN_REPORT ------------
Event: time 1671569327.729626, type 4 (EV_MSC), code 4 (MSC_SCAN), value ee
Event: time 1671569327.729626, type 1 (EV_KEY), code 212 (KEY_CAMERA), value 0

(Note, ignore this one since the key actually works)

Hotkey number 3 Power Mode:

Event: time 1671569328.108543, type 4 (EV_MSC), code 4 (MSC_SCAN), value 91

Hotkey number 4 Screen Rotation:
