--- Comment #12 from Greg V <greg@unrelenting.technology> ---
I think I found the culprit, it's the length retrieval in get_input_report. I
changed it to just trust the given length — touchscreen works, touchpad doesn't
receive evdev events yet (hmm) but doesn't crash the controller and I can see
the reports changing with a debug print, and reload the module multiple times.
Seems like ig4 is innocent and it's the touchpad firmware reacting to iichid
that's causing the bus to get screwed up. Closing the bug here.
