Thank you for your patch-series, I've applied patches 1-3 to my review-hans branch: https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans For patches 4 - 6 please address the review remarks and post a v10 based on top of my review-hans branch. 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.
