When I started splitting off this code (which, as explained in the cover
letter, is something I'm doing in preparation of an upcoming series) I
planned to use the device list for more than just iterating through its
members.

Turns out that I won't need to do that after all, so having the loop in
the caller makes more sense. I'll change it.

I concede that I could have done a better job at isolating independent
changes, I'll try to improve with v2 :)

In that regard, would you rather have the comments dealt with in a
separate commit, even if that would mean have them not reflect the
code mid-series?

Cheers.
