I don't seem to be able to figure out what indentation is being used here.
Why two tabs and two spaces? It doesn't align with anything this way.

Added one more space :-), and fixed indentation in another place,
too. Will push with next updates...

Never mind, I have noticed that it's already in Linus' tree even with the
little bit wonky formatting, so I am not going to take it to trivial tree
anyway.

So you are computing a position according acceleration readings?
Isn't that common code to all accelerometers and should be put
into a higher level?

Not really, the "position" is actually only the current acceleration
read from the sensor minus the calibration vector. It's more wording
problem, nothing fancy like double integration ;-)

Nevertheless, this remark is still valid, there are various code that
all the accelerometer drivers could share. I'm thinking in particular of
the sysfs interface, and joystick interface. There has been some work in
this direction with the "industrialio" subsystem. So for now I'm in
"wait and see" mode about this :-)
See you,
