Title:
  Please add min/max quirk for pnp-id LEN2006 (Lenovo Thinkpad Edge
  E440)

Status in “linux” package in Ubuntu:
  New

Bug description:
  This a request to get a quirk added upstream for the Synaptics
  ClickPad (buttonless trackpad) of the Lenovo Edge E440 to the
  synaptics kernel driver so the right coordinates for the surface
  corners are reported and the pointer functionality is correct.

  $ lsb_release -rd
  Description:	Ubuntu 14.04.1 LTS
  Release:	14.04

  $ apt-cache policy xserver-xorg-input-synaptics
  xserver-xorg-input-synaptics:
    Installed: 1.8.1-1ubuntu2~trusty1
    Candidate: 1.8.1-1ubuntu2~trusty1
    Version table:
   *** 1.8.1-1ubuntu2~trusty1 0

  Yes, I'm using a newer version from ppa:aglasgall/synaptics
  (https://launchpad.net/~aglasgall/+archive/ubuntu/synaptics) but this
  is irrelevant to the issue as it hasn't been solved upstream yet.

  I will be attaching a patch tomorrow.

  Similar changes have been requested for other Thinkpad models also
  shipping these new ClikcPads, via other distributions' bug trackers,
  forwarded upstream, and succesfully incorporated in mainstream kernel
  code. See e.g.
