Merge branch 'pci/misc'
- Mark fall-through switch cases before enabling -Wimplicit-fallthrough (Gustavo A. R. Silva) - Move DMA-debug PCI init from arch code to PCI core (Christoph Hellwig) - Fix pci_request_irq() usage of IRQF_ONESHOT when no handler is supplied (Heiner Kallweit) - Unify PCI and DMA direction #defines (Shunyong Yang) - Add PCI_DEVICE_DATA() macro (Andy Shevchenko) - Check for VPD completion before checking for timeout (Bert Kenward) - Limit Netronome NFP5000 config space size to work around erratum (Jakub Kicinski) * pci/misc: PCI: Limit config space size for Netronome NFP5000 PCI/VPD: Check for VPD access completion before checking for timeout PCI: Add PCI_DEVICE_DATA() macro to fully describe device ID entry PCI: Unify PCI and normal DMA direction definitions PCI: Use IRQF_ONESHOT if pci_request_irq() called with no handler PCI: Call dma_debug_add_bus() for pci_bus_type from PCI core PCI: Mark fall-through switch cases before enabling -Wimplicit-fallthrough # Conflicts: # drivers/pci/hotplug/pciehp_ctrl.c
