Subject: [PATCH v3 0/4] Fixes for ALPS driver

This patch series tries to fix problems with ALPS dualpoint devices on Dell
Latitude laptops which are probably caused by bugs in Dell BIOS, Dell EC or
in ALPS touchpad firmware itself.

Root of problems is yet unknown but at least this patch series could eliminate
reporting bogus data to userspace.

Reported bugs:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1258837
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1320022

https://bugzilla.redhat.com/show_bug.cgi?id=1145954

Pali Rohár (4):
  input: alps: Do not try to parse data as 3 bytes packet when driver
    is out of sync
  input: alps: Allow 2 invalid packets without resetting device
  input: alps: For protocol V3, do not process data when last packet's
    bit7 is set
  input: alps: Fix trackstick detection
