| Subject: Input: elantech - enable 3rd button support on Fujitsu CELSIUS H780 |
| |
| From: Matti Kurkela <Matti.Kurkela@iki.fi> |
| |
| 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. |
