No camera device in OpenSUSE for Surface Go

I'm using an openSUSE kernel with my Surface Go and it mostly working fine except camera. I've installed libcamera and intel firmware but cam --list shows no devices. Here are some outputs that may help to determine issue cause:

Will be appreciate to hear any advises what to do

Environment

Hardware model: Surface GO 2
Kernel version: 6.7.2+ (4e36132e272de3d84833b799be56c2b460db08b6)
Distribution: Gentoo

I think I have the same problem. See dmesg.txt.
Applying this patch fixes the "failed initialize subdev media entity" error.
But lens focus still doesn't work. See dmesg-patched.txt
This issue is also mentioned in here.

Same issue on Kubuntu, kernel 6.7.2-surface-1, on Surgace GO 1

I found that the dw9719(lens voice coil) driver was rewritten in linux-6.6, and unfortunately, that doesn't work with Surface Go.
In order to restore camera functionalities in 6.7.x, I had to apply some patches:

# v6.7 camera workarounds
## fix "failed initialize subdev media entity" error
## cherry-pick from staging tree
curl 'https://git.linuxtv.org/media_stage.git/patch/?id=87318b7092670d4086bfec115a0280a60c51c2dd' | patch -p1
## revert dw9719 driver
curl 'https://raw.githubusercontent.com/linux-surface/kernel/v6.5-surface/drivers/media/i2c/dw9719.c' -o drivers/media/i2c/dw9719.c
sed -i 's/.probe_new/.probe/' drivers/media/i2c/dw9719.c
## optional: suppress the "source of link 'ipu3-imgu 0 input':0->'ipu3-imgu 0':0 is not a V4L2 sub-device, driver bug!" warning
curl 'https://github.com/linux-surface/kernel/commit/55f1ecb1199000932cf82e357841cc7498ac904f.patch' | patch -R -p1
## optional: suppress annoying stacktrace around call_s_stream on application exit
curl 'https://github.com/linux-surface/kernel/commit/009905ec50433259c05f474251000b040098564e.patch' | patch -R -p1

@mojyack

@mojyack Could you send a PR with those changes to our kernel repo?

I have sent fixes.
Sad to had to revert dw9719 driver.

Same Issue with my SGO1 on Fedora39 with fedora kernel 6.7.3-200.fc39.x86_64.

Same here (SGO1, Ubuntu 23.10). Booting with previous kernel, 6.6.11, cameras work. Does the PR have a good chance of being merged?

The patch from the LKML that is supposed to fix the ipu3 issue is now proposed for

6.7.12: https://lore.kernel.org/stable/[email protected]/
6.8.3 : https://lore.kernel.org/stable/[email protected]/

So hopefully it should arrive at a stable kernel near you soon.

Fedora updated me to 6.8.4-200.fc39.x86_64 today and cameras are working again.

Is there any update to make cameras work in OpenSuse? I have no cameras listed too (SGO2)
