This through me as I was trying to reconcile this series with another mellanox
platform driver from Vadim to the drivers/platform/x86 tree as this one also
came to the platform-driver-x86 mailing list.

There are no other entries in MAINTAINERS that use this list without files under
drivers/platform/x86.

Thomas, HPA, Ingo, do you also use the platform-driver-x86 mailing list for
arch/x86/platform? I had assumed this was only for drivers/platform/x86.

I can definitely understand how contributors might get confused.... I think I
may have confused myself actually :-)

My two cents too late, this driver seems like it would better placed in
drivers/platform/x86 as it isn't architectural (or SoC specific) in the same way
most of the others in arch/x86/platform are, but instead is more akin to the
end-product laptop drivers and such in drivers/platform/x86 which build platform
data from DMI strings, ACPI HIDs, etc.

If this isn't the right distinction between the two similarly named trees ...
how would you like to distinguish them? I'll volunteer to get that documented
someplace convenient to make it easier to decide what goes where.
