    The commit (especially the subject) should be more descriptive, it's not
    that we're missing error checks it's that you're handling garbage passed
    in from the user a bit more gracefully.

    I'm not sure how useful this is as-is - if you're not checking your
    errors you're not checking your errors so it's probably just pushing the
    robustness failures around, especially since...

    > + return -ENODEV;

    ...this is too quiet, this should at the very least be generating a loud
    warning so people can see there's a problem (probably with WARN_ON so we
    can see what called it). Can you respin with something noisier please?

    Also NULL is a valid regulator (though we don't use it right now).
