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

Note I had to apply this manually do to a conflict with:
3427c443a6dc platform/surface: platform_profile: add fan profile switching

which I merged into pdx86/for-next after this series was send out.

Please double check I resolved the conflict correct.

Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.

Regards,

Hans
