Thanks for the review. I agree that this one can be merged
already, so I have just merged it:

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 it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.

Patches which are added to review-hans now are intended for
the next rc1. This branch will get rebased to the next rc1 when
it is out and after the rebasing the contents of review-hans
will be pushed to the platform-drivers-x86/for-next branch.

Regards,

Hans
