My understanding is that you should use __must_check if it is potentially dangerous to ignore the return value. Which is not the case here, if you don't look at the return value it's kind of pointless to call the function in the first, but it is not dangerous. - Lars -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
