I'm not sure if I understood you correctly.
I did these:
* remove the quirk for touchpack in hid-quirks.c
* change hid-multitouch.c as suggested by Benjamin.
Test results:
* The touchscreen is detected by hid-core.
(only one device is detected)
* Manually modprobe hid-multitouch,
it didn't detect the touch device.
* The android framework correctly recognized
the touchscreen and it works well.
The whole patch shows as below:
