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);Sui Jingfeng (5): PCI: Add the pci_get_base_class() helper ALSA: hda/intel: Use pci_get_base_class() to reduce duplicated code drm/nouveau: Use pci_get_base_class() to reduce duplicated code drm/amdgpu: Use pci_get_base_class() to reduce duplicated code drm/radeon: Use pci_get_base_class() to reduce duplicated code
