Hi Takashi, 5 patches here for the scarlett2 driver... Patches 1-4 are renames/cleanup/refactoring in preparation for adding firmware update, Scarlett Gen 4, and Vocaster support. Patch 5 fixes the Level Meter control which was barely useful before, but now works as expected. Thanks, Geoffrey. Geoffrey D.
