HP Spectre x360 (2023): webcam INT3537 does not work

I'm having trouble to get my webcam to work on my new laptop running Fedora 39.

- Laptop: 13.5" HP x360 [14-ef2759nz](https://support.hp.com/us-en/drivers/hp-spectre-x360-13.5-inch-2-in-1-laptop-pc-14-ef2000/model/2101549652?sku=7P401EA&serialnumber=CND3290HZY)
- Camera description: "HP True Vision 5MP IR camera with camera shutter, temporal noise reduction and integrated dual array digital microphones".
- Model `INT3537` (According to `dmesg`.)
- Sensor `HI556`
- This model has been mentioned in these issues: #182 #48 (maybe #105)

I'm using Fedora 39 and installed the latest kernel and ipu6 as explained here.

```bash
sudo dnf update \
--enablerepo=updates-testing \
--enablerepo=rpmfusion-free-updates-testing \
--enablerepo=rpmfusion-nonfree-updates-testing \
'kernel*' '*v4l2loopback'

# And now things are ready to install the IPU6 driver stack:

sudo dnf install \
--enablerepo=updates-testing \
--enablerepo=rpmfusion-free-updates-testing \
--enablerepo=rpmfusion-nonfree-updates-testing \
akmod-intel-ipu6

# Secure boot must be disabled.
# Reboot.
```

Installed packages:

- kernel-6.6.2-201.fc39.x86_64
- kmod-intel-ipu6-6.6.2-201.fc39.x86_64-0.0-10.20230622git8e41080.fc39.x86_64
- kmod-v4l2loopback-6.6.2-201.fc39.x86_64-0.12.7^20230503g2c9b670-2.fc39.x86_64

The webcam seems to be detected:

However, it doesn't work with Cheese nor Firefox.

```

`dmesg` seems to detect a problem:
