This patch change the return for IIO_CHAN_INFO_OFFSET to -EINVAL except for temperature to avoid offset.
I think we should rather fix iio_channel_read() to check if the channel supports the property that we try to read. Other drivers are likely to suffer from the same issue and fixing it in a central place fixes them all.
