> Subject: [PATCH 0/5] Add the pci_get_base_class() helper and use it

> 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);
