Hi Tobias, Thanks for the review. Yes, I think it is a bit nit-picking, and I'd
prefer to have just one return in the function. I don't think replacing the
return with a goto adds much and in the interests of keeping churn down, I
won't be making the change unless it prevents the driver moving out of staging.

Cheers,

Mark
