From e8b22d0a329f0fb5c7ef95406872d268f01ee3b1 Mon Sep 17 00:00:00 2001 From: Matti Kurkela Date: Thu, 7 Feb 2019 23:49:23 -0800 Subject: [PATCH] Input: elantech - enable 3rd button support on Fujitsu CELSIUS H780 Like Fujitsu CELSIUS H760, the H780 also has a three-button Elantech touchpad, but the driver needs to be told so to enable the middle touchpad button. The elantech_dmi_force_crc_enabled quirk was not necessary with the H780. Also document the fw_version and caps values detected for both H760 and H780 models.
