Subject: [patch 3/3] Input: psmouse - allow disabling of synaptics protocol extension
Date: Thu, 15 Feb 2007 05:13:06 -0500 [thread overview]
Message-ID: <45D43232.2070100@debian.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 244 bytes --]
Allow disabling of synaptics via CONFIG_MOUSE_PS2_SYNAPTICS;
we leave synaptic_detect and synaptic_reset (for synaptics hardware
that emulates other protocols), but get rid of synaptic_init.
