[alsa-devel] Line 6 Helix quirks

[nick83ola]

Hi Jens,
in my hx stomp with 2.82 firmware the USB id is the same and I'm not
experiencing any glitch.
Also some people on line6 confirm that the patch is working for hx stomp.
If on helix the situation is different you should submit a patch.

Best Regards
Nicola Lunghi
