One more idea, would it be better here to do the following?

	if (device_property_present(i2c->dev, "lltc,meas-mode")) {
		ret = of_property_read_u32_array(of_node, "lltc,meas-mode",
						 data->mode, 2);
	}

I'm happy to prepare a patch if you wish to have this in - just let me know whether it should be on top of the last one, or instead of it.

Thanks,
Max
