--------------------------------

commit fdd478c3ae98c3f13628e110dce9b6cfb0d9b3c8 upstream.

There are cases in the compensate functions of the driver that
there could be overflows of variables due to bit shifting ops.
These implications were initially discussed here [1] and they
were mentioned in log message of Commit 1b3bd859 ("iio:
chemical: Add support for Bosch BME680 sensor").
