Re: [PATCH] hwmon: (yogafan) Add support for new Lenovo models

Hi Guenter,

Confirming that at my knowledge this is a non-issue.
However, using the 4-letter machine type code DMI_PRODUCT_NAME could
theoretically
offer even tighter precision, but up to now, the current matching
method has never failed in our
testing and field deployment users of my github:
https://github.com/sergiomelas/lenovo-linux-drivers/tree/main

Anyway, I am compiling a full database for complete data of Lenovo
machines from PSREF:
https://psref.lenovo.com/
For reference, the complete mapping matrix and DSDT traces can be
found in the Yogafan Master Quirk Database.
My database on based on this source and others is here:
https://github.com/sergiomelas/lenovo-linux-drivers/blob/main/Lenovo_Drivers/Prototype/PSREF/yogafan_v3_quirks_database.ods
and
https://github.com/sergiomelas/lenovo-linux-drivers/tree/main/Lenovo_Drivers/Prototype/DSDT

I propose to switch to this identification method when we have more
machine references.
What do yo think?

Thanks, Sergio
