Bug#1089964: nvidia-tesla-470-kernel-dkms: Build error with kernel 6.12

[Laurent Cheylus]

Package: nvidia-tesla-470-kernel-dkms
Version: 470.256.02-4
Followup-For: Bug #1089964

Same issue when building nvidia-tesla-470-driver with kernel 6.12.6 on
Debian/testing.

Fix issue with patch from https://gist.github.com/joanbm/a6d3f7f873a60dec0aa4a734c0f1d64e

- Patch file /usr/src/nvidia-tesla-470-470.256.02/nvidia-drm/nvidia-drm-drv.c
- Rebuild driver via 'dpkg-reconfigure nvidia-tesla-470-driver'

- Add option for Nvidia driver in /etc/modprobe.d/nvidia-options.conf

options nvidia_drm modeset=1

After reboot, nvidia-tesla-470-driver is loaded as kernel module with version
6.12.6 and used for X server (tested with my GeForce GTX 760 graphic card).
