8 | commit 384cf4285b34e08917e3e66603382f2b0c4f6e1b upstream. | |
9 | ||
10 | The Lenovo LaVie Z laptop requires i8042 to be reset in order to | |
11 | consistently detect its Elantech touchpad. The nomux and kbdreset | |
12 | quirks are not sufficient. | |
13 | ||
14 | It's possible the other LaVie Z models from NEC require this as well. | |
