[ Upstream commit 5827e17d0555b566c32044b0632b46f9f95054fa ]

vmd_domain_reset() attempts to find whether the device may contain multiple
functions by checking 0x80 (Multi-Function Device), however, the hdr_type
variable has already been masked with PCI_HEADER_TYPE_MASK so the check can
never true.

To fix the issue, don't mask the read with PCI_HEADER_TYPE_MASK.

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:
   - Add locking to read/modify/write PCIe Capability Register accessors
     for Link Control and Root Control
   - Use pci_dev_id() when possible instead of manually composing ID
     from dev->bus->number and dev->devfn

  Resource management:
   - Move prototypes for __weak sysfs resource files to linux/pci.h to
     fix 'no previous prototype' warnings
   - Make more I/O port accesses depend on HAS_IOPORT
   - Use devm_platform_get_and_ioremap_resource() instead of open-coding
     platform_get_resource() followed by devm_ioremap_resource()

  Power management:
   - Ensure devices are powered up while accessing VPD
   - If device is powered-up, keep it that way while polling for PME
   - Only read PCI_PM_CTRL register when available, to avoid reading the
     wrong register and corrupting dev->current_state

  Virtualization:
   - Avoid Secondary Bus Reset on NVIDIA T4 GPUs

  Error handling:
   - Remove unused pci_disable_pcie_error_reporting()
   - Unexport pci_enable_pcie_error_reporting(), used only by aer.c
   - Unexport pcie_port_bus_type, used only by PCI core

  VGA:
   - Simplify and clean up typos in VGA arbiter

  Apple PCIe controller driver:
   - Initialize pcie->nvecs (number of available MSIs) before use

  Broadcom iProc PCIe controller driver:
   - Use of_property_read_bool() instead of low-level accessors for
     boolean properties

  Broadcom STB PCIe controller driver:
   - Assert PERST# when probing BCM2711 because some bootloaders don't
     do it

  Freescale i.MX6 PCIe controller driver:
   - Add .host_deinit() callback so we can clean up things like
     regulators on probe failure or driver unload

  Freescale Layerscape PCIe controller driver:
   - Add support for link-down notification so the endpoint driver can
     process LINK_DOWN events
   - Add suspend/resume support, including manual
     PME_Turn_off/PME_TO_Ack handshake
   - Save Link Capabilities during probe so they can be restored when
     handling a link-up event, since the controller loses the Link Width
     and Link Speed values during reset

  Intel VMD host bridge driver:
   - Fix disable of bridge windows during domain reset; previously we
     cleared the base/limit registers, which actually left the windows
     enabled

  Marvell MVEBU PCIe controller driver:
   - Remove unused busn member

  Microchip PolarFlare PCIe controller driver:
   - Fix interrupt bit definitions so the SEC and DED interrupt handlers
     work correctly
   - Make driver buildable as a module
   - Read FPGA MSI configuration parameters from hardware instead of
     hard-coding them

  Microsoft Hyper-V host bridge driver:
   - To avoid a NULL pointer dereference, skip MSI restore after
     hibernate if MSI/MSI-X hasn't been enabled

  NVIDIA Tegra194 PCIe controller driver:
   - Revert 'PCI: tegra194: Enable support for 256 Byte payload' because
     Linux doesn't know how to reduce MPS from to 256 to 128 bytes for
     endpoints below a switch (because other devices below the switch
     might already be operating), which leads to 'Malformed TLP' errors

  Qualcomm PCIe controller driver:
   - Add DT and driver support for interconnect bandwidth voting for
     'pcie-mem' and 'cpu-pcie' interconnects
   - Fix broken SDX65 'compatible' DT property
   - Configure controller so MHI bus master clock will be switched off
     while in ASPM L1.x states
   - Use alignment restriction from EPF core in EPF MHI driver
   - Add Endpoint eDMA support
   - Add MHI eDMA support
   - Add Snapdragon SM8450 support to the EPF MHI driversupport
   - Add MHI eDMA support
   - Add Snapdragon SM8450 support to the EPF MHI driversupport
   - Add MHI eDMA support
   - Add Snapdragon SM8450 support to the EPF MHI driversupport
   - Add MHI eDMA support
   - Add Snapdragon SM8450 support to the EPF MHI driver
   - Use iATU for EPF MHI transfers smaller than 4K to avoid eDMA setup
     latency
   - Add sa8775p DT binding and driver support

  Rockchip PCIe controller driver:
   - Use 64-bit mask on MSI 64-bit PCI address to avoid zeroing out the
     upper 32 bits

  SiFive FU740 PCIe controller driver:
   - Set the supported number of MSI vectors so we can use all available
     MSI interrupts

  Synopsys DesignWare PCIe controller driver:
   - Add generic dwc suspend/resume APIs (dw_pcie_suspend_noirq() and
     dw_pcie_resume_noirq()) to be called by controller driver
     suspend/resume ops, and a controller callback to send PME_Turn_Off

  MicroSemi Switchtec management driver:
   - Add support for PCIe Gen5 devices

  Miscellaneous:
   - Reorder and compress to reduce size of struct pci_dev
   - Fix race in DOE destroy_work_on_stack()
   - Add stubs to avoid casts between incompatible function types
   - Explicitly include correct DT includes to untangle headers"
