I wasn't sure if the Reviewed-by: tag means that I should apply the patch
through the hwmon subsystem. If so, please let me know. For now I'll
assume that it will be applied through a platform tree.

Thanks,
Guenter

I think it would make more sense for it to go through pdx86 (as usual
for platform/surface). That would avoid any potential merge conflicts
if we get more changes to the surface_aggregator_registry later on.

Hans, Ilpo, could you please take this?

Also I just noticed that Ilpo wasn't CCd, I assume because of an older
MAINTAINERS list. Ivor, please add him for any next submissions to
platform/surface.

Best regards,
Max

Okay, thanks for letting me know (I assumed the opposite). I'll take it 
through pdx86.

Yes, mea culpa. Guenter also ran into trouble applying the v4 version of
the patch yesterday. I'm sorry I didn't base this off the correct branch
everyone, will be sure to do so in the future!
