I know it may seem silly, but to me it is more logical to always
guard PTR_ERR() uses with IS_ERR().

Therefore could you please restructure this as:

	if (IS_ERR(power)) {
		if (PTR_ERR(power) == -EPROBE_DEFER)
			return -EPROBE_DEFER;
		else
			dev_dbg(dev, "no regulator provided\n");
	} else {

Thanks.
