That is a much cleaner approach and avoids issues that can happen if core I2C support is build as a module and core SPI support is built-in. - 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
