Subject: [PATCH] ALSA: usb-audio: Add DSD support for Accuphase DAC-60
Git-commit: 8cbd4725ffff3eface1f5f3397af02acad5b2831
Patch-mainline: v6.1-rc5
References: git-fixes

Accuphase DAC-60 option card supports native DSD up to DSD256,
but doesn't have support for auto-detection. Explicitly enable
DSD support for the correct altsetting.
