Scrolling doesn't work with the 3 button trackpad on the T440p #77

Describe the bug Scrolling doesn't work with the 3 button trackpad, and dragging causes the cursor to lag. However, the buttons work as intended.

Edit: Zooming in works but zooming out doesn't

macOS Version: 12.6.6 Monterey
EFI Version: 0.7.8
EFI type: Regular

I was able to fix it by downloading the VoodooPS2Controller.kext file from here: https://github.com/jloisel/t440p/files/5637832/EFI-20201203T172653Z-001.zip, copying and overwriting the original VoodooPS2Controller.kext file into the EFI folder on the EFI partition, then using OC Auxiliary Tools to update the VoodooPS2Controller.kext and the VoodooRMI.kext files. Despite originally being for Big Sur, it works fine once you update once you update the kext files.
