Somebody in the thread at some point said:

| or zero disruption to current code. ]
| - input_report_rel(lis->input_dev, REL_X, mg_per_sample *
| + input_report_abs(lis->input_dev, ABS_X, mg_per_sample *
| + set_bit(EV_ABS, lis->input_dev->evbit);
The accelerations have a relative effect on position, but the
accelerations themselves are absolute it seems.
However, changing it would likely break most of the userspace
accelerometer code for no gain other than correct book-keeping really.
What's the downside of just leaving these as relative?
