From e584bc3cf6865e005bbb4dbabae0bf4b3df59500 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 1 Mar 2010 16:20:37 +0100 Subject: ALSA: ua101: add Edirol UA-1000 support Add support for the Edirol UA-1000 to the UA-101 driver. Both devices behave the same, so we just have to shuffle around some interface numbers and name strings.
