Do you mean that I'd rather left the whole patch as context, or that I
should provide a reason for the ping?

I will just take this fix and apply it to the series (git fixup) rather than
take this patch as is. Also, as registers should be unsigned short, I think
we should change the type to that.
I will fixup patches in place.
Sure thing.
