Ok, I've applied patch 5/8 + 6/8 to my review-hans branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans

I'll rebase that branch once 6.3-rc1 is out and then push the rebased
patch to the fixes branch and include it in my next 6.3 fixes pull-req
to Linus.

Regards,

Hans
