Now

			return dev_err_probe(...);

Ditto.

>  			dev_err(priv->dev,
>  				"failed to register LED device %s, err %d",
>  				led->ldev.name, ret);
> -			goto err_child_out;

Ditto.

			return dev_err_probe(priv->dev, ret, "failed to register LED device %s\n",
				led->ldev.name);

...

Also notice missed '\n' at the end of the strings (and yes, I know
