ok, I removed the debdiffs as they're not needed.

I did attach a single patch, that works around the bug in a simple way, by updating only the NVMe udev rules to force whitespace replacement with underscores. This allows the NVMe symlinks to work even for devices with whitespace in their model/serial strings, while leaving the rest of udev unchanged. This patch would allow the ubuntu udev pkgs to work correctly, while the bug is discussed upstream. Note that this workaround will not break anything even if upstream uses an alternate way of fixing this.
