The mcp2221_raw_event retrieves the value and direction of gpio on the
same command, by setting the value on mcp->status and the direction on
mcp->gpio_dir; and the offset at which they are read is based on
mcp->gp_idx, set by the gpiochip callbacks.

However, the individual gpiochip calls set the index to look for
directly on the field they want to track. This create a "double offset"
in the final read in the response report.

Align the behaviour of mcp2221_raw_event and
mcp_gpio_get/mcp_gpio_get_direction by putting gp_idx on those calls to
the base offset of the gpio status struct.

The documentation of the component (section 3.1.12 GET GPIO VALUES)
describes the hid report structure with two fields per gpio:
its value, followed by its direction.

However, the driver describes it with a wrong order:
direction followed by value.

Fix the structure representing the report answered by the chip to the
GET GPIO VALUES command.

  Testing is of course being upgraded, and the upgraded tests detect

Pull compute express link (cxl) fixes from Dan Williams:
 "Several fixes for driver startup regressions that landed during the
  merge window as well as some older bugs.

  The regressions were due to a lack of testing with what the CXL
  specification calls Restricted CXL Host (RCH) topologies compared to
  the testing with Virtual Host (VH) CXL topologies. A VH topology is
  typical PCIe while RCH topologies map CXL endpoints as Root Complex
  Integrated endpoints. The impact is some driver crashes on startup.

  This merge window also added compatibility for range registers (the
  mechanism that CXL 1.1 defined for mapping memory) to treat them like
  HDM decoders (the mechanism that CXL 2.0 defined for mapping
  Host-managed Device Memory). That work collided with the new region
  enumeration code that was tested with CXL 2.0 setups, and fails with
  crashes at startup.

  Lastly, the DOE (Data Object Exchange) implementation for retrieving
  an ACPI-like data table from CXL devices is being reworked for v6.4.
  Several fixes fell out of that work that are suitable for v6.3.

  All of this has been in linux-next for a while, and all reported
  issues [1] have been addressed.

  Summary:

   - Fix several issues with region enumeration in RCH topologies that
     can trigger crashes on driver startup or shutdown.

   - Fix CXL DVSEC range register compatibility versus region
     enumeration that leads to startup crashes

   - Fix CDAT endiannes handling

   - Fix multiple buffer handling boundary conditions

   - Fix Data Object Exchange (DOE) workqueue usage vs
     CONFIG_DEBUG_OBJECTS warn splats"

Currently if disk_scan_partitions() failed, GD_NEED_PART_SCAN will still
set, and partition scan will be proceed again when blkdev_get_by_dev()
is called. However, this will cause a problem that re-assemble partitioned
raid device will creat partition for underlying disk.

Test procedure:

mdadm -CR /dev/md0 -l 1 -n 2 /dev/sda /dev/sdb -e 1.0
sgdisk -n 0:0:+100MiB /dev/md0
blockdev --rereadpt /dev/sda

Test result: underlying disk partition and raid partition can be

Note that this can still happen in come corner cases that

The stack trace is a bit misleading as dw_pcie_host_deinit() doesn't
directly call pci_bus_release_domain_nr(). The issue turns out to be in
pci_remove_root_bus() which first calls pci_remove_bus() which frees the
struct pci_bus when its struct device is released. Then
pci_bus_release_domain_nr() is called and accesses the freed struct
pci_bus. Reordering these fixes the issue.

The AMD [1022:15b8] USB controller loses some internal functional MSI-X
context when transitioning from D0 to D3hot. BIOS normally traps D0->D3hot
and D3hot->D0 transitions so it can save and restore that internal context,
but some firmware in the field can't do this because it fails to clear the
AMD_15B8_RCC_DEV2_EPF0_STRAP2 NO_SOFT_RESET bit.

Clear AMD_15B8_RCC_DEV2_EPF0_STRAP2 NO_SOFT_RESET bit before USB controller
initialization during boot.

pci_msix_can_alloc_dyn() is not declared when CONFIG_PCI_MSI is disabled.

There is no existing user of pci_msix_can_alloc_dyn() but work is in
progress to change this. This work encounters the following error when
CONFIG_PCI_MSI is disabled:

  drivers/vfio/pci/vfio_pci_intrs.c:427:21: error: implicit declaration of function 'pci_msix_can_alloc_dyn' [-Werror=implicit-function-declaration]

Provide definition for pci_msix_can_alloc_dyn() in preparation for users
that need to compile when CONFIG_PCI_MSI is disabled.
