Hi Vladimir,
sorry for a delay (was not able to catch up on email for several days)
first of all thanks for your time/efforts!
Regarding the patch:
1) the kernel compiles OK, no side-effects/regressions were observed (in
the course of brief manual testing of clickpad/trackpoint)
2) the behavior of trackpoint has changed. In particular it is the
following:
- no pointer "flickering" is observed anymore and it stands still once
one just touches it (previously it used to flicker for a few fractions
of seconds after one touches it and then pointer was moved exactly to
the left upper screen corner and it was not possible to move it anymore
by means of a trackpoint. I.e. one could manipulate pointer only via
either externally connected mouse or via swiping touchpad (or it seems
the proper term for it clickpad since it's bottom area "clicks" when one
presses it).
- pointer can be manipulated via a trackpoint. However it's behavior is
quite weird. In particlular:
* pointer can be moved up/down and right left;
* pointer can be moved north-east (up-right) and south-west(down-left)
* on attempts to move pointer either north-west (up-left) or
south-east (down-right) it remains motionless.
not sure if I have to blame hardware. Because a month ago when I
received a device (it was supplied with Win10 system) worked as
expected. Right now I can't prove that again because Win10 was erased
unused OS to leave more space on disk.
just in case mentioning relevant sysctl settings:

3) this one has probably nothing to do with the clickpad driver: those
errors in Xorg.log still persist when one puts the palm on a touchpad. I.e.:
