From: Jonathon Jongsma <jjongsma@xxxxxxxxxx>
Since this is public API, we can't easily change the signature of the
function to take a RedsState argument, so instead we apply a hack and
store the reds argument inside the device state struct when the
interface is added, and retrieve it for use later when it is removed.
