Subject: ALSA: usb-audio: Add DSD support for Accuphase DAC-60
From: Jussi Laako <jussi@xxxxxxxxxxxxx>
commit 8cbd4725ffff3eface1f5f3397af02acad5b2831 upstream.
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.
