'sca3000_configure_ring()' can fail, so test its return value and
propagate it if needed.

Un-tested and not 100% sure that we should bail-out if it fails.

Good catch - and yes we should bail out on error here.

I'll pick this one up when we finish discussion of patch 1.
(or possibly in v2 if you agree with my suggestion there).

Thanks,

Jonathan
