From 1f9c3c73b61e084c25e55e8f9415d8ac6e0adbd5 Mon Sep 17 00:00:00 2001 From: Florian Ragwitz Date: Tue, 27 Apr 2010 00:47:04 -0700 Subject: [PATCH 3/4] Input: elantech - allow forcing Elantech protocol Apparently hardware vendors now ship elantech touchpads with different version magic. This options allows for them to be tested easier with the current driver in order to add their magic to the whitelist later.
