From 284a8dd6f0fb16029198b5b34437499d504b567c Mon Sep 17 00:00:00 2001 From: Mark Hills Date: Sat, 14 Apr 2012 17:19:23 +0100 Subject: [PATCH] ALSA: snd-usb-audio: Skip un-parseable mixer units instead of erroring Some interfaces reference endpoints which do not exists. To accomodate these, do not fail completely, but skip over them. This allows the Electrix Ebox-44 with earlier firmware to be detected and used for audio.
