From 8d0912427113723c3f3a4dca631638844c4ab649 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Wed, 26 May 2010 18:11:37 +0200 Subject: [PATCH] ALSA: usb-audio: fix return values -1 is not a good return value as it means -EPERM, "not permitted". Choose -ENOTSUPP instead, which is what the code really wants to tell its callers.
