[ Upstream commit c21733754cd6ecbca346f2adf9b17d4cfa50504f ]
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:

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