On the Acer Nitro AN515-58, the event 4 - 0 is send by the ACPI
firmware when the backlight up/down keys are pressed. Ignore this

acpi-video driver already handles brightness up/down events.


Thank you for your contribution, it has been applied to my local
review-ilpo-fixes branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-fixes branch only once I've pushed my
local branch there, which might take a while.
Thank you. I just noticed that i made a slight error inside the patch

Could you fix that up inside your branch?
Hi,

Hmm, I didn't notice it myself but think b4 did change it as this is

Strange, but the tags are indeed correct. In this case no further action seems to be necessary.

Thanks,
