From fb4f8f568a9def02240ef9bf7aabd246dc63a081 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 7 Jun 2014 23:07:13 -0700 Subject: [PATCH] Input: elantech - don't set bit 1 of reg_10 when the no_hw_res quirk is set The touchpad on the GIGABYTE U2442 not only stops communicating when we try to set bit 3 (enable real hardware resolution) of reg_10, but on some BIOS versions also when we set bit 1 (enable two finger mode auto correct). I've asked the original reporter of: https://bugzilla.kernel.org/show_bug.cgi?id=61151 To check that not setting bit 1 does not lead to any adverse effects on his model / BIOS revision, and it does not, so this commit fixes the touchpad not working on these versions by simply never setting bit 1 for laptop models with the no_hw_res quirk.
