Yeah, sure, sorry for the split series, but the lt6106 that's present in
one of our newer designs didn't occur to me until just seconds after
firing the first half of the series. Which is kind of typical...

Anyway, about the driver naming. The suggestion I like best so far is
linear-scaler from Linus W, but thinking about it some more I think I
like iio-rescale even better.

Any objections to iio-rescale?
