The confusion comes from the fact that struct i2c_adapter should have
been named struct i2c_segment, as this is what it really represents.
But back when it was decided, multiplexing wasn't considered so the
developers thought "controller", "adapter" and "segment" were the same
thing.
Ideally we should rename i2c_adapter to i2c_segment, but this seems a
little intrusive for a rather thin benefit.
