The above is an unrelated whitespace change and doesn't belong in this
patch. Ideally you'd send a v5 where you didn't have that.

In any case, it's not a huge deal to me, so with or without that fix:

Reviewed-by: Douglas Anderson <dianders@...omium.org>

If you do decide to send a v5, please make sure you carry my and
Krzysztof's Reviewed-by tags on the bindings and my Reviewed-by tag on
this patch. Thanks!
