[PATCH 00/23] ALSA: scarlett2: Refactor in preparation for gen4

["Geoffrey D. Bennett" <g@xxxxx>]

Hi Takashi,

This series is preparation for adding support for the Focusrite
Scarlett 4th Gen devices. It applies on top of the previous series
https://lore.kernel.org/linux-sound/cover.1703001053.git.g@xxxxx/
"ALSA: scarlett2: Firmware Upgrade and Error Handling Improvements".

There should be no notable functional changes in this series, just
refactoring/restructuring/renaming/reformatting.

Regards,
Geoffrey.
