This is pretty contorted, we should just be able to pass the return
value back more directly and of course ideally gpiolib would be doing
the -EPROBE_DEFER for us anyway (I did send a patch for this, Grant
didn't apply it due to a mostly unrelated issue in the current probe
deferral implementation).  Or just defer if we don't get a config passed
back or something.
