[PATCH] HID: multitouch: Add MT_QUIRK_NOT_SEEN_MEANS_UP to Surface Pro 3

From: Benjamin Tissoires
Date: Tue May 31 2016 - 11:31:25 EST


The firmware found in the touch screen of an SP3 is buggy and may miss
to send lift off reports for contacts. Try to work around that issue by
using MT_QUIRK_NOT_SEEN_MEANS_UP.

based on a patch from: Daniel Martin <consume.noise@xxxxxxxxx>
