Build fail log

Found someone having the same issue on nvidia forums they have also made a patch.

To my understanding builds of NVIDIA kernel module version 545.29.06 fail with gcc-14 due to an incompatible pointer types error in kernel/nvidia-drm/nvidia-drm-gem.c. The issue is linked to the renaming of 'dma_buf_map' to 'iosys_map' in recent Linux kernels.

I have attached my module build log, if that may prove useful.

I wont address this before F40 beta release (12/03/2024).
