> There is no function that can be used to get all PCI(e) devices in a system by
> matching against its the PCI base class code only, while keep the sub-class code
> and the programming interface ignored. Therefore, add the
> pci_get_base_class() function to suit the need.

> For example, if an application want to process all PCI(e) display devices in a
> system, it can achieve such goal by writing the code as following:

>     pdev = NULL;
>     do {
>         pdev = pci_get_base_class(PCI_BASE_CLASS_DISPLAY, pdev);
>         if (!pdev)
>             break;
>
>         do_something_for_pci_display_device(pdev);
>     } while (1);
