IIO: bmp280-core.c: fix error in humidity calculation

Browse source

commit ed3730c435 upstream.

While calculating the compensation of the humidity there are negative values
interpreted as unsigned because of unsigned variables used.  These values as
well as the constants need to be casted to signed as indicated by the
documentation of the sensor.
