From: Sui Jingfeng <suijingfeng@xxxxxxxxxxx> Instead of accessing the PCI_CLASS_DISPLAY_VGA and pdev->class directly. The PCI_CLASS_NOT_DEFINED_VGA is defined to provide backward compatibility for devices that were built before the class code field was defined. It should be visiable via sysfs(boot_vga) as the normal VGA-compatible devices. Cc: "Maciej W.
