Synaptics touchpads report increasing y from bottom to top.
This is inverted from normal userspace "top of screen is 0" coordinates.
Thus, the kernel driver reports inverted y coordinates to userspace.

This patch refactors this inversion.

I really do not see the point...

The point is that this inversion is done in 3 places in the driver.
Refactoring lets us document why this inversion is happening in just a
single place.

Thanks.
