Subject: [PATCH] ALSA: usb-audio: Generic DSD detection for XMOS-based implementations
Git-commit: f332485fb37baecc3e2e598870f33d06c15a74f3
Patch-mainline: v4.18-rc1
References: bsc#1051510

Use more generic method to detect DSD capability of XMOS-based UAC2
implementations in order to support future devices without having to
explicitly list every device separately.
