Re: [PATCH] media: ivsc: csi: Add sensor node in bound callback

[Sergey Zagursky]

Hi Arpith,

Same regression on a Dell XPS 16 9640 (BIOS 1.4.1, OV02C10 behind the
IVSC, HIMX1092:00 in ACPI). I reported it before finding your patch:
https://lore.kernel.org/r/20261109142140.ov02c10-hm1092-regression.e938253b8516@xxxxxxxxx/

I tested the same change (identical apart from the declaration of ret)
on CachyOS 7.2.8, with modules built from kernel.org v7.2.8 sources:
- 7.2.8 plus only the HM1092 entry from 4fdb0342f05e: no sub-device
  node for the OV02C10, libcamera skips the sensor.
- Same plus this change: the node is created, libcamera and PipeWire
  find the camera, and "cam -c1 --capture=10" streams at 30 fps.
- This change without the HM1092 entry, so .complete() runs after the
  node already exists: still one node for the sensor, streams fine.
No kernel warnings in any of these.

Sakari, if you pick this up, could you also add
Closes: https://lore.kernel.org/r/20261109142140.ov02c10-hm1092-regression.e938253b8516@xxxxxxxxx/

I used an AI assistant (Claude) to analyse the problem; the tests
above ran on my machine.

Thanks,
Sergey
