It is not "totally wrong". But it is useless code that should not be
in kernel. Calibration certainly does not belong to single
_driver_. Feel free to submit driver but keep the calibration code out
of tree...

But if you have userspace that depends on touchscreen to be
calibrated... that _is_ wrong.
