From 2a2a5dddece676acbe3775e5ca9961f325717022 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 8 Jan 2007 17:42:22 +0100 Subject: [PATCH] [ALSA] usbaudio - Fix kobject_add() error at reconnection Fixed the error from kobject_add() at reconnection the usb audio device. This happens when an app keeps opening a device while the device is replugged, due to the confliction of the internal bookkept index and the really empty slot.
