That message correlates to this code.
BUG_WARN_MSG(!(event->device_event.flags & TOUCH_POINTER_EMULATED),
"Non-emulating touch event\n");
Not sure what it implies but seems to be "just" a warning.
Other than that, 4-finger tap appears to work fine for me. Any other
suggestions for reproducing with the current code?
