From 55e3d9224b60df0fd2dc36bff9b538ce40fd9586 Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Sat, 10 Mar 2007 01:39:54 -0500 Subject: Input: psmouse - allow disabing certain protocol extensions Allow ALPS, LOGIPS2PP, LIFEBOOK, TRACKPOINT and TOUCHKIT protocol extensions of psmouse to be disabled during compilation. This will allow users save some memory when they are sure that they will only use a certain type of mice.
