From: Sui Jingfeng suijingfeng@loongson.cn

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);

Thanks a lot.

What to do next then?

By the way, Bjorn, what's your opinion? I'm ask because I don't know what to do next with this series.

As they belong to different system of Linux kernel, the rest of patch (0002 ~ 0005) depend on the first one.

I think, merge the 0001-patch firstly, then wait it arrive at drm-misc, alsa branch. Or, to do something else?
