That's really strange. I just tested on an ARM board where I currently
run 3.12-rc2 as well, and I can load the module without problems. Also,
sound/usb/card.c (where the params are declared) hasn't seen an update
in 3.12.

I suspect your OS is passing "index=-2" from something like
/etc/modprobe.d/* or cmdline settings. Could you investigate in that
direction?


HTH,
Daniel
