| Subject: Input: i8042 - add Lenovo ThinkPad L460 to i8042 reset list |
| |
| commit b56af54ac78c54a519d82813836f305d7f76ef27 upstream. |
| |
| Reset i8042 before probing because of insufficient BIOS initialisation of |
| the i8042 serial controller. This makes Synaptics touchpad detection |
| possible. Without resetting the Synaptics touchpad is not detected because |
| there are always NACK messages from AUX port. |
