I think this particular problem is fixed by the following patch to the
X driver:

I think this CodingStyle violation is quite annoying, because it
prevents emacs from finding the beginning of the function. It should
be written like this:

static int atp_calculate_abs(int *xy_sensors, int nb_sensors, int fact)
