Ah well. Applied to the fixes-togreg branch of iio.git Thanks, Jonathan

The macro MAX1X29_CHANNELS() already calls MAX1X27_CHANNELS(). Calling MAX1X27_CHANNELS() before MAX1X29_CHANNELS() in the definition of MAX1X31_CHANNELS() declares the first 8 channels twice. So drop this extra call from the MAX1X31 channels list definition.
