Subject[PATCH] platform/x86: huawei-wmi: Silence ambient light sensor
Date
Currently huawei-wmi causes a lot of spam in dmesg on my
Huawei MateBook X Pro 2022:

...
[36409.328463] input input9: Unknown key pressed, code: 0x02c1
[36411.335104] input input9: Unknown key pressed, code: 0x02c1
[36412.338674] input input9: Unknown key pressed, code: 0x02c1
[36414.848564] input input9: Unknown key pressed, code: 0x02c1
[36416.858706] input input9: Unknown key pressed, code: 0x02c1
...

Fix that by ignoring events generated by ambient light sensor.

This issue was reported on GitHub and resolved with the following merge
request:

https://github.com/aymanbagabas/Huawei-WMI/pull/70

I've contacted the mainter of this repo and he gave me the "go ahead" to
send this patch to the maling list.
