Si7020 outputs most significant byte of the measurement result first and least significant byte last. As a result the data returned by i2c_smbus_read_word_data appears as big endian. Fix this by making a call to an approbriate byte conversion routine.
i2c_smbus_read_word_data() returns data in native endianess. But it interprets the word on the bus as little-endian (As specified by the SMBus spec). If your chip returns data in big-endian use i2c_smbus_read_word_data_swapped().
