From c5d40be5f5255c156a5ad851f395fb21bc44f379 Mon Sep 17 00:00:00 2001 From: Henrik Rydberg Date: Wed, 5 Sep 2012 16:58:12 +0200 Subject: [PATCH] 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.
