From f153fc3990d4ad2709a52d7150e2c04363afb1fb Mon Sep 17 00:00:00 2001 From: Henrik Rydberg Date: Wed, 9 Mar 2011 06:35:25 +0100 Subject: HID: hid-multitouch: Send events per slot if CONTACTCOUNT is missing The recent capacitive DWAV firmwares do not use the CONTACTCOUNT field, and the touch frame boundary can therefore not be determined. This patch makes the driver report the touch frame at each completed slot instead.
