This is clearly an issue for at least one existing driver - in that the lightening sensor uses proximity for distance to lightening. However, this is the most common interpretation now. I would suggest our best way forward is to add a distance channel to the lightening driver, but keep the proximity channel there to avoid breaking userspace. Anyhow, this patch itself is fine.
