The snd-usb-audio driver no longer loads properly on 3.12-rc2 when I plug in my USB headset. It worked fine on 3.11-rc4 (not sure about vanilla 3.11).

Trying to manually load the driver fails:

sarah@xanatos:~$ sudo modprobe snd-usb-audio FATAL: Error inserting snd_usb_audio (/lib/modules/3.12.0-rc2/kernel/sound/usb/snd-usb-audio.ko): Invalid argument

dmesg shows:

[ 44.231668] snd_usb_audio: `-2' invalid for parameter `index'

There is no corresponding code change in the USB audio driver side, so I guess it must be in the module parameter parser that got broken.

Does the patch below fix?

thanks,

Takashi
