Merge branch 'pci/enumeration'
- Add and use pci_get_base_class() to search for all PCI_BASE_CLASS_DISPLAY devices (Sui Jingfeng) - Fix a vmd check for multi-function devices (Ilpo Järvinen) - Add PCI_HEADER_TYPE_MFD and use it to replace literals (Ilpo Järvinen) - Use acpi_evaluate_dsm_typed() instead of open-coding it (Andy Shevchenko) - Keep .remove() and .probe() callbacks (previously marked __init) in case they're used via sysfs (Uwe Kleine-König) * pci/enumeration: PCI: keystone: Don't discard .probe() callback PCI: keystone: Don't discard .remove() callback PCI: kirin: Don't discard .remove() callback PCI: exynos: Don't discard .remove() callback PCI/ACPI: Use acpi_evaluate_dsm_typed() PCI: Use PCI_HEADER_TYPE_* instead of literals PCI: Add PCI_HEADER_TYPE_MFD definition PCI: vmd: Correct PCI Header Type Register's multi-function check drm/radeon: Use pci_get_base_class() to reduce duplicated code drm/amdgpu: Use pci_get_base_class() to reduce duplicated code drm/nouveau: Use pci_get_base_class() to reduce duplicated code ALSA: hda: Use pci_get_base_class() to reduce duplicated code PCI: Add pci_get_base_class() helper
