[alsa-devel] [PATCH] More generic way to detect DSD capabilities

[Jussi Laako]

There is a more generic way to detect DSD capability of popular UAC2
implementations. Advantage is that each new device with DSD capability
doesn't have to be explicitly listed through VID:PID.

XMOS/Thesycon implementation uses this method. As a safety precaution
I have still left VID detection in place. Many of the implementations
use XMOS' VID, but not all. I have moved over the devices that have
been tested with these patches. Likely more of at least XMOS VID ones
could be removed from the explicit list, but I opted for careful
approach.
