No longer working on kernel version 6.0 or 6.1

[oliv3r]

Compilation doesn't produce any errors or warnings, however cheese reports the following:

(cheese:5211): cheese-WARNING **: 11:48:15.090: Internal data stream error.: ../gstreamer/subprojects/gstreamer/libs/gst/base/gstbasesrc.c(3127): gst_base_src_loop (): /GstCameraBin:camerabin/GstWrapperCameraBinSrc:camera_source/GstBin:bin35/GstPipeWireSrc:pipewiresrc1:
streaming stopped, reason not-negotiated (-4)

Which doesn't really help either.

Probing the module yields:

which doesn't seem troublesome ...

The driver was working quite well before ...

[larsblumberg]

Running kernel 6.0.6 and the driver (still) works for me.

> uname -r
6.0.6-76060006-generic

I used these instructions.

[oliv3r]

Seems to be working again. I don't know why it wasn't working before ... Maybe an arch bug :) Sorry for the noise, but hope to see it upstreamed soon :p
