From: Matti Kurkela Date: Fri, 8 Feb 2019 07:49:23 +0000 (-0800) Subject: Input: elantech - enable 3rd button support on Fujitsu CELSIUS H780 X-Git-Tag: v3.18.135~10 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2d8cfdac38725bc3e74adacdf37266a51067f375;p=thirdparty%2Fkernel%2Fstable.git Input: elantech - enable 3rd button support on Fujitsu CELSIUS H780 commit e8b22d0a329f0fb5c7ef95406872d268f01ee3b1 upstream. 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.
