Error building on Ubuntu 19.04

Here's what I'm getting after a kernel upgrade

I fixed it by removing the old compiled facetimehd files.

Here's the script that I use if anyone wants it. It assumes you've cloned this repo to ~/src/ already:

#!/usr/bin/env bash

printf "Upgrading library..."
cd ~/src/bcwc_pcie
git pull

printf "Compiling firmware\n";
cd ~/src/bcwc_pcie/firmware
make
printf "done\n\n";

printf "Installing firmware\n";
sudo make install
printf "done\n\n";

cd ..

printf "Compiling driver\n";
make
printf "done\n\n";

printf "Installing driver\n";
sudo make install
printf "done\n\n";

printf "Running depmod\n";
sudo depmod
printf "done\n\n";

printf "Running modprobe -r bdc_pci\n";
sudo modprobe -r bdc_pci
printf "done\n\n";

printf "Loading driver\n";
rm facetimehd.*
sudo modprobe facetimehd
printf "done\n\n";
