Ok, your ALPS touchpad is identified as:
{ { 0x22, 0x02, 0x14 }, 0x00, { ALPS_PROTO_V2, 0xff, 0xff, ALPS_PASS | ALPS_DUALPOINT } }, /* Dell Latitude D600 */
You mentioned that commit 92bac83d introduced your problem:
========================================
commit 92bac83dd79e60e65c475222e41a992a70434beb
Author: Hans de Goede <hdegoede@xxxxxxxxxx>
Date: Sun Apr 12 15:42:35 2015 -0700
Input: alps - non interleaved V2 dualpoint has separate stick button bits
========================================
Hans, can you look at this problem as it is clearly problem with
protocol V2?
