Subject: [PATCH AUTOSEL 6.10 079/197] ALSA: usb-audio: Add quirk for RME Digiface USB
From: Cyan Nyan <cyan.vtb@...il.com>
[ Upstream commit c032044e9672408c534d64a6df2b1ba14449e948 ]
Add trivial support for audio streaming on the RME Digiface USB. Binds
only to the first interface to allow userspace to directly drive the
complex I/O and matrix mixer controls.
