Yes, 2.5.42 did this also. It looks like gcc 3.2 doesn't like goto's
which reference variables outside their native scope. You can move the
Controller definition to full function scope to fix that error.
The DAC960 doesn't seem usable out of the stock kernel build though.
You'll need to try patches previously posted to the list. (Which don't
fully work for me either...)
