Title:
  Enable multitouch function on precision touchpad for Vivid

Status in HWE Next:
  New
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  [Impact]

  Multitouch feature is not enabled on some platforms with new Win8
  precision touchpad because it can't fetch the report from the device.
  In worst case it can even break the multitouch device.

  [Fix]

  There's one commit to fix this issue:
  commit 171202b6fee80d777d18bb8a53b3e4361d97f389
  Author: Mika Westerberg <mika.westerberg@xxxxxxxxxxxxxxx>
  Date:   Wed Oct 7 15:33:43 2015 +0300

      HID: multitouch: Fetch feature reports on demand for Win8 devices

  In addition, this commit may cost some issue on ELAN touchpad, and
  there's another commit to improve the fix:

  commit e47b1e449ea70d76c38a50c04cde60a72bc7ebde
  Author: Benjamin Tissoires <benjamin.tissoires@xxxxxxxxxx>
  Date:   Tue Dec 1 12:41:38 2015 +0100

      HID: multitouch: fix input mode switching on some Elan panels

  Both commits can be clean picked, and are already in Xenial.

  [Test]

  The patched Vivid kernel is tested on two platforms and both worked
  before and after suspend.
