Add the following line in Makefile under /usr/src/linux/drivers/input/serio:
```
obj-m += ft8042.o
```
Assuming kernel configuration has been done, cd /usr/src/linux && make -j$(nproc)
make modules_install && make install
Make sure module ft8042 in configured in /etc/modules-load.d/ .
Reboot and check if it works.
