If anyone has any objections, please let me know. ------------------ From: Geoffrey D. Bennett [ Upstream commit 6e743781d62e28f5fa095e5f31f878819622c143 ] This driver was originally developed for the Focusrite Scarlett Gen 2 series, but now also supports the Scarlett Gen 3 series, the Clarett 8Pre USB, and the Clarett+ 8Pre. The messages output by the driver on initialisation and error include the identifying text "Scarlett Gen 2/3", but this is no longer accurate, and writing "Scarlett Gen 2/3/Clarett USB/Clarett+" would be unwieldy. Add series_name field to the scarlett2_device_entry struct so that concise and accurate messages can be output. Signed-off-by: Geoffrey D.
