Awww <multiple expletives removed>

I just re-read this - Has this series been blocked on me without me
realising?

/me cowers in a corner in shame...

I think the aim of this series was to simplify the code structures.

Making the vendor names usable, makes sense IMO, but I don't think that
was a goal of the original series.

I think the series was trying to make an improvement *without* changing
functionality / usage.

Re-introducing vendor names into the i2c matching would be a change in
scope from my view, but if it's required to get this series moving let
me know.
