ALSA: scarlett2: Add correct product series name to messages
[ 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.
