2.6.10, oops in snd_usb_audio after unplugging audio device

[Olaf Hering <olh@suse.de>]

Got a soundblaster live 24bit today, it works ok with 2.6.10-rc3.

I got this crash while playing a wav file in a loop.
while true;do aplay /usr/share/sounds/alsa/test.wav;done
The volume tuner on the box does not work for some reason, it acts also
as mute button. Mute did not react anymore after a few tries, so I
unplugged it. The result was the crash below.

This is an ibook running sles9 ppc.
