The MAINTAINERS update seems like it deserves a separate patch.
But most importantly, you need to add a patch that converts the error
reporting to use dev_err_probe(). Currently code has that issue, i.e.
it will print the error message as many times as probe was deferred
due to unreadiness of GPIO.

Something like this

>                 dev_err(dev, "cannot get aux-gpios %d\n", ret);
>                 return ret;

===>

  return dev_err_probe(dev, ret, "cannot get aux-gpios\n");

with a Fixes tag added.
