[Bug 2145171] Re: MIPI camera is not working after upgrading to 6.17-oem

SRU:
* https://lists.ubuntu.com/archives/kernel-team/2026-March/166587.html (noble, questing, resolute)
* https://kernel.ubuntu.com/forgejo/kernel/noble-linux-oem/pulls/398 (oem-6.17)

** Description changed:

+ SRU Justification:
+
+ [Impact]
+
+ Upstream v6.18-rc1 commit 4405a214df146775338a1e6232701a29024b82e1
+ "ACPI: scan: Add Intel CVS ACPI HIDs to acpi_ignore_dep_ids[]" (also
+ backported to v6.17.8, v6.12.58), which in effect reverts a not yet
+ upstreamed Intel MIPI camera patch titled "ACPI: scan: Update HID for
+ new platform" meant for bug 2090932, and therefore they share the same
+ symptom:
+
+ [ 4.484426] ov02c10 i2c-OVTI02C1:00: chip id mismatch: 560243!=0
+ [ 4.484432] ov02c10 i2c-OVTI02C1:00: failed to find sensor: -6
+
+ [Fix]
+
+ While this should really be fixed by upstream Intel's CVS driver and
+ remove the two platforms from acpi_ignore_dep_ids, a sauced change is
+ made to preserve the honor effect and yet don't introduce potential
+ conflict with the upstream before any further progress is made.
+
+ [Test Plan]
+
+ 1. Install the kernel from -proposed pocket and reboot into it.
+
+ 2. Check dmesg has no aforementioned error,
+
+ 3. Make sure the device appears in the gstreamer device enumeration:
+
+ $ gst-inspect-1.0 icamerasrc
+ .....
+ device-name : The input devices name queried from HAL
+ flags: readable, writable
+ Enum "GstCamerasrcDeviceName" Default: 0, "ov02c10-uf"
+ (0): ov02c10-uf - ov02c10 as sensor.
+
+ [Where problems could occur]
+
+ No. This restores the hardware enablement effort for the affected
+ platforms only. For Ubuntu, CVS driver is always available along with
+ the kernel, and therefore for a device declared _DEP to the two ACPI
+ devices, the driver can be installed either through ubuntu-drivers or
+ through oem meta packages.
+
+ [Other Info]
+
+ While this has been backported to v6.17.8, it affects R and Q. And while
+ this has also been backported to v6.12.58, and linux-6.8/noble is
+ tracking stable 6.8 fixes, Noble will be affected soon or later.
+ Nominate for N, Q and R accordingly.
+
+ ========== original bug report ==========
+
[Summary]
During the kernel SRU testing, we found out that 3 xps13-9350 camera-related tests failed.

I saw following in dmesg.
ov02c10 i2c-OVTI02C1:00: failed to find sensor: -6
-

[Reproduce steps]
1. Install GM image
2. Run dist-upgrade to upgrade to 6.17-oem kerenl
3. Run checkbox sru test plan or use https://webcamtests.com/ to test the camera
