Can you provide some more in info on this? Then Mark can maybe check
if we need to add more models ?
Mark, generally speaking it may help to do a DMI_EXACT_MATCH on
DMI_PRODUCT_VERSION with ThinkPads ? That contains the human
readable model string instead of things like "20UJ", and I guess
that we want to e.g. apply the s2idle quirk to all "T14s Gen1 AMD"
ThinkPads.

Thank you for your patch, I've applied this patch to my fixes
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=fixes
Note it will show up in my fixes branch once I've pushed my
local branch there, which might take a while.
I will include this patch in my next fixes pull-req to Linus
for the current kernel development cycle.
Regards,
Hans
