Subject: [PATCH] ALSA: usb-audio: add quirk flag to enable native DSD for McIntosh devices
Git-commit: 99248c8902f505ec064cf2b0f74629016f2f4c82
Patch-mainline: v6.7-rc1
References: git-fixes
McIntosh devices supporting native DSD require the feature to be
explicitly exposed. Add a flag that fixes an issue where DSD audio was
defaulting to DSD over PCM instead of delivering raw DSD data.
