Thank you for your patch, I've applied this patch to my review-hans branch: https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans The patches sitting here allows the LKP testing infra to test the patches. I will move these over to a 6.0-rc1 based feature branch once 6.0-rc1 is out. Note I did do a few small last fixes while merging this, see my replies to individual patches. Please test the version in the review-hans branch and base any future patches on top of the version in the review-hans branch.
