Subject: [PATCH] ALSA: scarlett2: Add Focusrite Clarett+ 8Pre support
Git-commit: f71c70df416f4d49a9cf11d6132f6aaba0e2f65c
Patch-mainline: v6.0-rc1
References: git-fixes
The Focusrite Clarett+ 8Pre uses the same protocol as the Scarlett Gen
2 and Gen 3 product range. This patch adds support for the Clarett+
8Pre by adding appropriate entries to the scarlett2 driver.
The Clarett+ 2Pre and 4Pre, and the Clarett USB product line
presumably use the same protocol as well, so support for them can
easily be added if someone can test.
