PCI: Add pci_get_base_class() helper
There is no function to get all PCI devices in a system by matching against the base class code only, ignoring the sub-class code and the programming interface. Add pci_get_base_class() to suit the need. For example, if a driver wants to process all PCI display devices in a system, it can do so like this: pdev = NULL; while ((pdev = pci_get_base_class(PCI_BASE_CLASS_DISPLAY, pdev))) { do_something_for_pci_display_device(pdev); } Link: https://lore.kernel.org/r/20230825062714.6325-2-sui.jingfeng@linux.dev Signed-off-by: Sui Jingfeng <suijingfeng@loongson.cn> [bhelgaas: reword commit log] Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com>
