Hi Wolfram,

Sorry for the late reply, I was on the road for most of the past 2
weeks.

I see that the patch is already upstream. Nevertheless I reviewed the
integration part of it and it looks OK to me. Thanks for doing that!

The only thing which I find curious is that ACPI_I2C_OPREGION depends
on I2C=y. Is this limitation a leftover from when the code was split to
a separate file? It builds just fine with I2C=m, and I can't see why it
wouldn't work. I have a patch to enable that, I can send it if it is
the right thing to do. But maybe I'm missing something?

Thanks again,
