Merge branch 'pci/misc'
- Reorder struct pci_dev to avoid holes and reduce size (Christophe JAILLET) - Change pdev->rom_attr_enabled to single bit since it's only a boolean value (Christophe JAILLET) - Use struct_size() in pirq_convert_irt_table() instead of hand-writing it (Christophe JAILLET) - Explicitly include correct DT includes to untangle headers (Rob Herring) - Fix a DOE race between destroy_work_on_stack() and the stack-allocated task->work struct going out of scope in pci_doe() (Ira Weiny) - Use pci_dev_id() when possible instead of manually composing ID from dev->bus->number and dev->devfn (Xiongfeng Wang, Zheng Zengkai) - Move pci_create_resource_files() declarations to linux/pci.h for alpha build warnings (Arnd Bergmann) - Remove unused hotplug function declarations (Yue Haibing) - Remove unused mvebu struct mvebu_pcie.busn (Pali Rohár) - Unexport pcie_port_bus_type (Bjorn Helgaas) - Remove unnecessary sysfs ID local variable initialization (Bjorn Helgaas) - Fix BAR value printk formatting to accommodate 32-bit values (Bjorn Helgaas) - Use consistent pointer types for config access syscall get_user() and put_user() uses (Bjorn Helgaas) - Simplify AER_RECOVER_RING_SIZE definition (Bjorn Helgaas) - Simplify pci_pio_to_address() (Bjorn Helgaas) - Simplify pci_dev_driver() (Bjorn Helgaas) - Fix pci_bus_resetable(), pci_slot_resetable() name typos (Bjorn Helgaas) - Fix code and doc typos and code formatting (Bjorn Helgaas) - Tidy config space save/restore messages (Bjorn Helgaas) * pci/misc: PCI: Tidy config space save/restore messages PCI: Fix code formatting inconsistencies PCI: Fix typos in docs and comments PCI: Fix pci_bus_resetable(), pci_slot_resetable() name typos PCI: Simplify pci_dev_driver() PCI: Simplify pci_pio_to_address() PCI/AER: Simplify AER_RECOVER_RING_SIZE definition PCI: Use consistent put_user() pointer types PCI: Fix printk field formatting PCI: Remove unnecessary initializations PCI: Unexport pcie_port_bus_type PCI: mvebu: Remove unused busn member PCI: Remove unused function declarations PCI/sysfs: Move declarations to linux/pci.h PCI/P2PDMA: Use pci_dev_id() to simplify the code PCI/IOV: Use pci_dev_id() to simplify the code PCI/AER: Use pci_dev_id() to simplify the code PCI: apple: Use pci_dev_id() to simplify the code PCI/DOE: Fix destroy_work_on_stack() race PCI: Explicitly include correct DT includes x86/PCI: Use struct_size() in pirq_convert_irt_table() PCI: Change pdev->rom_attr_enabled to single bit PCI: Reorder pci_dev fields to reduce holes
