Right, the naming is a little tricky since neither source is fully complete.
I wrote a sync script that cross-references the PCI ID DB and OKM repo to
construct unique macro names. For the few entries with totally identical
descriptions across both sources, the device ID is appended as a fallback.
Here is an example for the GH100 family:

#define NVIDIA_GPU_GH100_H20 0x2329 /* H20 */
#define NVIDIA_GPU_GH100_H20_HBM3E 0x232c /* H20 HBM3e */
#define NVIDIA_GPU_GH100_H100_SXM5_80GB 0x2330 /* H100 SXM5 80GB */
#define NVIDIA_GPU_GH100_H100_PCIE 0x2331 /* H100 PCIe */
#define NVIDIA_GPU_GH100_H200_SXM_141GB 0x2335 /* H200 SXM 141GB */
#define NVIDIA_GPU_GH100_H100 0x2336 /* H100 */

The script also updates pci_id_cuda_map[] in cuda.c and I wrote a
test to verify both files are consistent.
