Subject: Re: [PATCH] firmware/dmi: Include product_sku info to modalias

Hello Jean,

There are multiple product skus share the same product name, like 
clamshell and 2-in-1 for Latitude series.
Both of them have 3-axis accelerator, but rotation is only disable for 
clamshell model.
Originally, it should be descriminated by chassis_type, but found that 
chassis_type is not trustful.
https://github.com/systemd/systemd/pull/17084#issuecomment-706931881
Therefore, I would like to propose a change to include the product_sku 
for applying customized configuration easier.

Thanks,
KaiChuan
