IIt seems I was too lazy to write a regression test for it, and this strikes back. Can you also work on a regression test for this at https://gitlab.freedesktop.org/libevdev/hid-tools ?

Of course. I'll do it later this week. Currently I have both affected Elan and Synaptics touchpad in hand. Will this be a blocker of getting the patch merged?

I made a pull request: https://gitlab.freedesktop.org/libevdev/hid-tools/-/merge_requests/105 The tests don't pass for both Elan and Synaptics device, but let's fix it there.

I have now added the "Cc: stable@vger.kernel.org" tag and pushed to for-5.11/upstream-fixes.

Palm ejection stops working on some Elan and Synaptics touchpad after commit 40d5bb87377a ("HID: multitouch: enable multi-input as a quirk for some devices"). The commit changes the mt_class from MT_CLS_WIN_8 to MT_CLS_WIN_8_FORCE_MULTI_INPUT, so MT_QUIRK_CONFIDENCE isn't applied anymore. So also apply the quirk since MT_CLS_WIN_8_FORCE_MULTI_INPUT is essentially MT_CLS_WIN_8.
