What happened?

/tmp/vbox.0/vbox_fb.c:337:16: error: implicit declaration of function ‘drm_fb_helper_alloc_info’; did you mean ‘drm_fb_helper_fill_info’?
/tmp/vbox.0/vbox_fb.c:337:14: error: assignment to ‘struct fb_info *’ from ‘int’ makes pointer from integer without a cast

How can we reproduce this?

1. Host: Windows 10 Build 19045.7663, running VirtualBox 7.2.16.
2. Guest: LMDE 7 with kernel 6.12.107+deb13-amd64 installed and running.
3. Insert Guest Additions CD image (Devices → Insert Guest Additions CD image).
4. Mount the CD and run the installer: sudo /mnt/VBoxLinuxAdditions.run
5. Observe the compilation failure during the graphics driver build.
