Bug Description

[Impact]

nvidia-dkms-515 fails to build with linux 6.2, reporting the following error:

/var/lib/dkms/nvidia/515.86.01/build/nvidia-drm/nvidia-drm-drv.c:245:21: error: ‘struct drm_mode_config’ has no member named ‘fb_base’
  245 | dev->mode_config.fb_base = 0;
      | ^
make[2]: *** [scripts/Makefile.build:260: /var/lib/dkms/nvidia/515.86.01/build/nvidia-drm/nvidia-drm-drv.o] Error 1

[Fix]

Change the driver to support also the 6.2 kernel ABI.

[Test case]

With linux 6.2 installed, run:

$ sudo apt install nvidia-dkms-515

[Regression potential]

We may experience regressions in newer kernels (>= 6.2) that are using nvidia-dkms-515 (source code for previous kernels remain unchanged).

I didn't realize that we use a separate folder to apply patches to the -open variant of the driver. So here's an additional debdiff (on top of the previous one) to also support nvidia-dkms-515-open with linux 6.2.
