New issue by hervyqa on void-packages repository

https://github.com/void-linux/void-packages/issues/52737

Description:
### Is this a new report?

Yes

### System Info

Void 6.6.54_1 x86_64 GenuineIntel uptodate rrmFFFF

### Package(s) Affected

-

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

-

### Expected behaviour

touchpad on void linux is detected and cursor appears.

### Actual behaviour

I installed void linux on a Chinese laptop which uses a hantix touchpad (which I detected on fedora using `libinput list-devices`). touchpad on void linux is not detected and cursor does not appear. while on fedora linux and manjaro it is detected. I don't know where the problem is, maybe there is a missing kernel configuration.

### Steps to reproduce

1. install void linux.

libinput on fedora linux.
```
$ libinput list-devices
```
```

it happens that I'm experiencing a similar but way more weird issue with `HTIX5288` *(since an upgrade on Arch)*.

## Summary

<!--Summarize the bug encountered concisely. See
https://wayland.freedesktop.org/libinput/doc/latest/reporting-bugs.html for
detailed instructions to report bugs-->

The HTIX5288:00 0911:5288 touchpad (vendor 0911, product 5288) on LapBook Pro laptops exhibits off-by-one finger detection. Kernel correctly reports BTN_TOOL_FINGER/DOUBLETAP/TRIPLETAP/QUADTAP events (verified with evtest), but libinput interprets them as N-1 fingers. Result: 1 finger = no movement, 2 fingers = pointer (should scroll), 3 fingers = scroll (should be gesture). Same hardware works correctly with xf86-input-synaptics on other distributions.

## Steps to reproduce

<!--How to reproduce the issue on a developer machine - this is very important-->

1. Use laptop with HTIX5288:00 0911:5288 touchpad (LapBook Pro)
2. Touch with 1 finger - observe erratic/no cursor movement
3. Touch with 2 fingers - observe pointer movement instead of scrolling
4. Touch with 3 fingers - observe two-finger scrolling instead of gesture
5. Verify with `sudo evtest /dev/input/eventX | grep BTN_TOOL` - shows correct kernel events

## Required information

<!--Note: if your libinput version is older than the current stable version,
please reproduce with a current version instead-->

- **libinput version:** 1.29.1
- **hardware information:**
  - Device: HTIX5288:00 0911:5288 Touchpad
  - Vendor/Product: 0911:5288
  - Bus: i2c
  - Kernel: 6.16.9-200.fc42.x86_64
  - Distribution: Fedora Silverblue 42
  - Desktop: GNOME Wayland
  - Size: 110x63mm
  - Max coordinates: X=2628 Y=1332
  - Resolution: 24x21 units/mm
  - DMI: Manufacturer: Not Specified, Product: LapBook Pro
- **`libinput record` output:** (attached as touchpad-record.txt)
- **`libinput debug-events --verbose` output:** (attached as debug-events.txt)

### evtest verification samples

**One finger (BTN_TOOL_FINGER reported, but no pointer movement):**

```
Event: type 1 (EV_KEY), code 325 (BTN_TOOL_FINGER), value 1
```

**Two fingers (BTN_TOOL_DOUBLETAP reported, but acts as single-finger pointer):**

```
Event: type 1 (EV_KEY), code 325 (BTN_TOOL_FINGER), value 0
Event: type 1 (EV_KEY), code 333 (BTN_TOOL_DOUBLETAP), value 1
```

**Three fingers (BTN_TOOL_TRIPLETAP reported, but acts as two-finger scroll):**

```
Event: type 1 (EV_KEY), code 333 (BTN_TOOL_DOUBLETAP), value 0
Event: type 1 (EV_KEY), code 334 (BTN_TOOL_TRIPLETAP), value 1
```

### Existing quirk for similar devices

File `/usr/share/libinput/30-vendor-synaptics.quirks` contains:

```
[Synaptics 0911:5288 Touchpad]
MatchUdevType=touchpad
MatchName=* 0911:5288 Touchpad
AttrEventCode=-BTN_RIGHT
```

This matches SYNA3602, ALPS0001, PCT2342 variants but not HTIX5288:00 prefix.

**Instructions for generating attachments:**

Before submitting, run these commands and attach the output files:

```bash
# Record touchpad events (touch with 1, 2, 3 fingers, then Ctrl+C after ~5 seconds)
sudo libinput record /dev/input/event9 > touchpad-record.txt

# Capture debug events (touch with 1, 2, 3 fingers, then Ctrl+C after ~5 seconds)
sudo libinput debug-events --verbose > debug-events.txt
```

Replace `event9` with your actual touchpad event node if different.
