A few nitpicks (because I anyway had some comment on patch4):

The above can be written on one line and the brackets isn't needed.

Replace host->variant->opendrain with variant->opendrain. The same
applies to the below change.

> +                */

I think we can remove this comment, as this information becomes
implicit when we start using the variant data.
