Release 4.11 drivers/input/mouse/synaptics.c
/*
* Synaptics TouchPad PS/2 mouse driver
*
* 2003 Dmitry Torokhov <dtor@mail.ru>
* Added support for pass-through port. Special thanks to Peter Berg Larsen
* for explaining various Synaptics quirks.
*
* 2003 Peter Osterlund <petero2@telia.com>
* Ported to 2.5 input device infrastructure.
*
* Copyright (C) 2001 Stefan Gmeiner <riddlebox@freesurf.ch>
* start merging tpconfig and gpm code to a xfree-input module
* adding some changes and extensions (ex. 3rd and 4th button)
