1 regulators is specified listed but the number 2 is specified. This
presumably means we try to get a regulator with no name. Fix it.

We should find some time and switch the reg_cfg.regs to be the external 
array, so that we can use ARRAY_SIZE for the amount of regs. However it 
is definitely not a showstopper for this series.
