I reported it before finding your patch: https://lore.kernel.org/r/20261109142140.ov02c10-hm1092-regression.e938253b8516@gmail.com/ 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. Tested-by: Sergey Zagursky Sakari, if you pick this up, could you also add Closes: https://lore.kernel.org/r/20261109142140.ov02c10-hm1092-regression.e938253b8516@gmail.com/ I used an AI assistant (Claude) to analyse the problem; the tests above ran on my machine. Thanks, Sergey
