Ah, good to know. I'll update the patch
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().

Ah, good to know. I'll update the patch accordingly.

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.
