In general we ask that binding modifications are in a separate patch,
earlier in the series (see [1]), but in cases where the additions are
small, we're not too bothered.

As for why, it's about making it easier to spot the parts we need to act
on. We still would like to see the entire series (and ask that we're
cc'd [1]), as this can be useful context for review, and there are often
mismatches between the documented binding and code that we may spot.

Thanks,
Mark.
