| Subject: Input: i8042 - add Lenovo LaVie Z to the i8042 reset list |
| |
| commit 384cf4285b34e08917e3e66603382f2b0c4f6e1b upstream. |
| |
| The Lenovo LaVie Z laptop requires i8042 to be reset in order to |
| consistently detect its Elantech touchpad. The nomux and kbdreset |
| quirks are not sufficient. |
| |
| It's possible the other LaVie Z models from NEC require this as well. |
