I knew this code existed, but I didn't realize it hadn't been initialized.
I'll fix it.

I'll fix it.
In the original code, I had set touch input to be disabled when the
value was 0, but after submitting the patch,
I realized that setting the resistance to infinity—rather than
disabling it at 0—would allow the interrupt handling to continue.
