iio: accel: kxsd9: Fix scaling bug
commit
307fe9dd11ae44d4f8881ee449a7cbac36e1f5de upstream.
All the scaling of the KXSD9 involves multiplication with a
fraction number < 1.
However the scaling value returned from IIO_INFO_SCALE was
unpredictable as only the micros of the value was assigned, and
not the integer part, resulting in scaling like this:
$cat in_accel_scale
-
1057462640.011978
Fix this by assigning zero to the integer part.
