Date: Wed, 5 Sep 2012 17:09:37 +0200 From: "Henrik Rydberg" <rydberg@...omail.se> To: Benjamin Tissoires <benjamin.tissoires@...c.fr> Cc: Dmitry Torokhov <dmitry.torokhov@...il.com>, Jiri Kosina <jkosina@...e.cz>, linux-input@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH v2 20/20] HID: hid-multitouch: Fix contact count on 3M panels Some devices report the number of contacts via the unreliable CONTACTCOUNT usage, rather than using the CONTACTMAX feature. Without this patch, the 3M devices are constrained to the default maximum of ten fingers.
