[PATCH] platform/x86: msi-wmi: Ignore WMI events for keys also handled by atkbd

[Patryk Pilichowski]

On MSI notebooks, several keys generate a WMI event through the Wind
event GUID in addition to a regular AT keyboard event. Their event
codes are not in the keymap, so every press logs "Unknown key
pressed".

These keys already work through the AT keyboard, so mark their WMI
codes as KE_IGNORE, as is already done for the MSI Claw. On models
where a code does not also produce a keyboard event, the event is
already dropped, so the only change there is that the log
message goes away.

The Wind event GUID is not specific to the MSI Wind. It is present in
17 of 18 MSI notebooks in the linuxhw ACPI dump collection (2012 to
2024), with the same _WED structure. The codes are shared across
models too: the volume keys on the tested notebook send the same codes
as the MSI Claw (0x21, 0x32).

Tested on an MSI Katana 15 B13VFK: Fn (0x0b), mic mute (0x19),
settings (0x1d), mute (0x23) and Bluetooth (0x78) no longer log
unknown key messages, and the keys keep working through atkbd.

Hi,

This is getting increasingly hard to read as the values are not ordered. 
And apparently grouping them by model was bogus anyway (as mentioned in 
your changelog text).

So my suggestion is you make a two patch series, first ordering these
existing ones numerically and adding the values for those not having one 
yet (please also convert 0xD0 -> 0xd0 for consistency). Then in the second 
patch add these new entries.
