Subject: [PATCH] HID: multitouch: add IGNORE_DUPLICATES quirk for ELAN1206
(04f3:30f1)
Some ELAN1206 I2C touchpads intermittently report duplicate tracking IDs.
On recent kernels this can make libinput interpret a one-finger slide as
repeated hold/click events instead of continuous POINTER_MOTION.
Add MT_QUIRK_IGNORE_DUPLICATES for 04f3:30f1 so the driver filters
repeated contacts and reports motion correctly. This restores behavior
comparable to 6.1 LTS kernels where motion and clicks were normal.
Reproducer notes: with hid_multitouch enabled, sliding a single finger
produces repeated GESTURE_HOLD_BEGIN/END in libinput and logs the
"double tracking ID ... in slot 0" error. Attached are short traces:
- elan1206-bug.yaml (libinput record)
- elan1206-bug.evemu (evdev stream)
- elan1206-bug.hidraw0 (HID raw capture)
- elan1206-bug.libinput (debug stream)
System: Fedora 42 (kernel 6.16.9-200.fc42.x86_64,
libinput 1.29.1,
device ELAN1206:00 04F3:30F1)

Is there a reason not to use USB_VENDOR_ID_ELAN here, instead of
