[PATCH 0/5] Add the pci_get_base_class() helper and use it
...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);
