Hi
I have the same issue building today’s v6.12-rc6 from kernel.org.
After a look in the code, the patch 446d0f48 had already been applied (code is the same as in v6.12-rc1)
After building debian kernel package of linux-6.12-rc6, while installing the debian created package, DKMS run to build NVIDIA module version 535.183.06.
It failed with error :
Configure linux-image-6.12.0-rc6-amd64 (6.12.0-rc6-1) ...
dkms: running auto installation service for kernel 6.12.0-rc6-amd64.

Having a look at the logfile, I found :
$ grep -i " error" /var/lib/dkms/nvidia-current/535.183.06/build/make.log
/var/lib/dkms/nvidia-current/535.183.06/build/nvidia-drm/nvidia-drm-drv.c:188:6: error: ‘const struct drm_mode_config_funcs’ has no member named ‘output_poll_changed’

cc1: some warnings being treated as errors
Google-ing the error message let me arrives here.
Any idea ?
Kind regards
