Thank you for your patch/series, I've applied this patch
(series) to my review-hans branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans

I will include this patch in my next fixes pull-req to Linus
for the current kernel development cycle.

Since patch 2/2 makes non pure bugfix functional changes
I expect Ilpo to pick that one up for pdx86/for-next.

Regards,

Hans
