Bug#1135362: linux-image-7.0.3+deb14-amd64: Fails to build nVidia module

[Jonas Andradas]

Hi Julian,

Please find attached the "consolidated" patch as "final-patch.patch) (I had
3-4 which I merged into one), in case it is useful. As I mentioned, I used
Claude Code to support this process, and iterated several times until a
working patch was produced.  (I also did the same using Gemini, but
Gemini's patch seems a little bit more messy, although it also "works"
(e.g. the module compiles).  I can share the patch produced with Gemini as
well for reference when I'm back home, although the one with Claude seemed
the cleanest.)

Thanks,
Jonas.
