Hi Mark,

It seems that while adding linux-kernel@vger.kernel.org you have dropped
platform-driver-x86@vger.kernel.org. For future patches please Cc both.

platform-driver-x86@vger.kernel.org needs to be Cc-ed for patches
to show up in patchwork:
https://patchwork.kernel.org/project/platform-driver-x86/list/

Which I use as my primary means of tracking which patches I need
to review / merge (note no need to resend this series I have it
on my radar).

More importantly you seem to not have Cc-ed
Thomas Weißschuh on this version ?

I have added Thomas to the Cc now, so that he can respond to this
version.

Regards,

Hans
