Applied now manually now, as the patch isn't cleanly applicable.
At best, please try to submit with git-send-email.

BTW, the entries there are sorted in the num ID order, so I moved the
new one to the right place, too.


thanks,

Takashi

These kind of device specific white-listing patches are unnecessary 
these days for VID 0x152a (Thesycon), 0x20b1 (XMOS) and 0x25ce (Mytek) 
because they are covered by the auto-detection code (below this 
whitelisting table). In fact, for some products they cause problems due 
to firmware changes that cause the DSD altsetting to change. Also there 
are vendors who use same VID:PID pair for multiple products with 
different firmware variants and different altsettings which in turn 
causes problems with these static altsetting listings.

So I would strongly advise to use the autodetection whenever possible. 
In my own kernel builds I've removed all those mentioned VIDs from the 
PID specific table, but for the already included patches I took more 
conservative approach and removed only the ones I could 100% test myself.

Sorry for the delay, I didn't notice this posting until now...

Care to send a cleanup patch?  That'll be really helpful.

[PATCH 0/1] ALSA: usb-audio: Cleanup DSD whitelist

[Jussi Laako]

Here's a cleanup patch for XMOS and Thesycon VID's from the explicit
VID:PID device whitelist. I personally don't have these remaining
devices, but based on what I know they should also work with the
auto-detection code.

In addition, I fixed ordering of the list so that it stays sorted.

I've also noticed earlier on thing, I strongly suspect there's a typo in
"NuPrime DAC-10" VID. It is "0x16b0" now, while there are other devices
with VID "0x16d0", including one other NuPrime device. Although nobody
seems to have complained about it either. Or maybe even the device itself
has a typo in VID, who knows...

[PATCH] ALSA: usb-audio: Cleanup DSD whitelist

[Jussi Laako]

XMOS/Thesycon family of USB Audio Class firmware flags DSD altsetting
separate from the PCM ones. Thus the DSD altsetting can be auto-detected
based on the flag and doesn't need maintaining specific altsetting
whitelist.

In addition, static VID:PID-to-altsetting whitelisting causes problems
when firmware update changes the altsetting, or same VID:PID is reused
for another device that has different kind of firmware.

This patch removes existing explicit whitelist mappings for XMOS VID
(0x20b1) and Thesycon VID (0x152a).

Also corrects placement of Hegel HD12 and NuPrime DAC-10 to keep list
sorted based on VID.
