Robert,

I now tried both 3.15 and 3.19-rc6. Both kernels require the byte swap code.

The only reason I can imagine why you don't need it in your code would be
that your i2c controller does not support i2c functionality but only SMBus.
This would be the case, for example, with the i801 controller. So it would
be quite helpful to know which controller your system uses to access the
ads7828.

Thanks,
Guenter
