> with pci_write_config() and pci_read_config() respectively:
>    - Rename variables (pos->off, cnt->count/size) for consistency
>    - Remove rebundant bounds check
>
> The last two patches fix potential overflow issues:
>    - Prevent overflow when offset exceeds reasonable range
>    - Fix implicit 64-bit to 32-bit truncation in read path
