Bug description:
Summary:
The integrated MIPI webcam on my Dell Precision 5490 does not work on Ubuntu 25.04 (kernel 6.14.0-15-generic). The camera is detected and all required IPU6 kernel modules and firmware are present, but applications like Cheese and GStreamer fail to capture video.

Steps to Reproduce:

    Boot Dell Precision 5490 with Ubuntu 25.04 (kernel
6.14.0-15-generic).

    Confirm IPU6 modules and firmware are loaded:

        lsmod | grep ipu shows all relevant modules (intel_ipu6,
intel_ipu6_isys, ov01a10, etc.).

        /usr/lib/firmware/intel/ipu/ contains all expected firmware
blobs.

    Launch Cheese or test with gst-launch-1.0 libcamerasrc !
videoconvert ! autovideosink.

Expected Result:
Webcam should function normally, displaying video.

Actual Result:

    Cheese and GStreamer both fail to display video.

    Cheese logs (libcamera v0.4.0) show repeated errors:

        Recommended V4L2 control 0x009a0922 not supported

        Unable to get rectangle X on pad 0/0: Ioctl() inapproprié pour
un périphérique

        The sensor kernel driver needs to be fixed

        Configuration file 'ov01a10.yaml' not found for IPA module
'simple', falling back to 'uncalibrated.yaml'

    GStreamer fails with buffer queue timeouts.

    The camera is detected, but no image is captured.
