the default value (250->2452) needs to be changed as well, I'll send an
updated patch

> The userspace interface for acceleration sensors is documented as using
> m/s^2 units [Documentation/ABI/testing/sysfs-bus-iio]
>
> The fullscale raw values for the BMA80 corresponds to -/+ 1, 1.5, 2, etc G
> depending on the selected mode.
>
> The scale table was converting to G rather than m/s^2.
> Change the scaling table to match the documented interface.
