The `als` build tree *seems* to imply they are re-using the pre-built
kernel modules from the vendor.
This is not something we really want to do.
The good thing is that LineageOS adds the required drivers to their
trees. We can re-use it!
libinput, which I believe, claims there is a kernel bug with the
synaptics driver touchscreen in use.
This is the recommended fix according to PostmarketOS.

I have not seen any issues from using this fix.
The error:
```
synaptics: kernel bug: device has min == max on ABS_MT_WIDTH_MAJOR
```
According to the touchscreen documentation of the kernel, I don't think
that it is an issue to remove this information from touch events.
