Need support for some buggy Synaptics RMI4 device

[Phidias]

[Impact]

Some RMI4 touchpad doesn't work properly even the probing returns no error. Further investigation shows the interrupt doesn't increase at all. There's already a public bug and the patch is already upstreamed:

https://bugs.freedesktop.org/show_bug.cgi?id=91102

[Fix]

There's a fix contains in v4.3-rc1 and has already been tested:

    HID: rmi: Set F01 interrupt enable register when not set

Note:
  So far the platform we encounter with this issue use GPIO interrupt, so it also needs 3.19.0-32 or Wily kernel to work too.

[Test]

1. Boot with v4.3-rc1 -> pass
2. Boot with patched Vivid kernel -> pass
3. Boot with patched Wily kernel -> pass

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1515503

and then change the status of the bug to 'Confirmed'.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-vivid' to 'verification-done-vivid'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Re-install Vivid and Wily, the original kernel can't use touchpad. After upgrading to proposed kernel, both versions' touchpad can work. Set to verification-done
