commit 81d5a5366d upstream.
The driver converts values read from the sensor from BE to CPU
endianness in scd4x_read_meas(). The result is then pushed into the
buffer in scd4x_trigger_handler(), so on LE architectures parsing the
buffer using the reported BE type gave wrong results.
scd4x_read_raw() which provides sysfs *_raw values is not affected, it
used the values returned by scd4x_read_meas() without further
conversion.
