Thank you for your patch series, I've applied this series
to my fixes branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=fixes
Note it will show up in my fixes branch once I've pushed my
local branch there, which might take a while.
I will include this series in my next fixes pull-req to Linus
for the current kernel development cycle.
Regards,
Hans
