Here is the second version of the patch series (reduced to just two patches now) that adds the special quirk needed for FreeCalypso DUART28C adapter. The first patch in this new reduced series is a preparatory change that makes it possible for quirk port_probe functions to determine which FT2232x or FT4232H channel is being considered, whereas all controversial changes are contained in the second and final patch.
