[Shrirang Bagul]

BugLink:  https://bugs.launchpad.net/bugs/1712481

[Impact]
Support to ALPS PTP Stick and Touchpad devices found on latest Dell
Latitude systems.

[Fix]
This fix in two parts:
1. Requires backport of patch submitted by ALPS in upstream kernel 4.13.
The backport is only due to the differences in the context.
See: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v4.13-rc6&id=504c932c7c47a6b4c572302a13873f7d83af1ff3
2. Additional sauce patch adds the device-id of the new PTP stick. This
patch is already submitted to linux-input and is pending review.

[Test Case]

conditional filtering based on these device-ids, regression potential is
minimal.
