I've been a little bemused about why I am getting credited for I2C
bus recovery work. I don't remember doing any work on that.

I did a couple of patches to fix a race when setting up a TX, but
those are, afaik, unrelated.

All I know about the bus recovery stuff is looking at it a while back
and thinking hmm, that seems to wiggle gpio without changing the
pinmuxing, so it can't possibly work.
