Based on num_hid_devices, each sensor device is initialized. If
"no sensors" is initialized, amd_sfh work initialization and scheduling
doesn’t make sense and returns EOPNOTSUPP to stop driver probe. Hence,
add a check for "no sensors" enabled to handle the special case.

The initialization of SFH1.1 sensors may take some time. Hence, increase
sensor command timeouts in order to obtain status responses within a

Misinterpreted the stop all command in SHF1.1 firmware. Therefore, it is
necessary to update the stop all command accordingly to disable all

As soon as the system is booted after shutdown, the sensors may remain in
a weird state and fail to initialize. Therefore, all sensors should be
turned off during shutdown.

In order to start or stop sensors, the firmware command needs to be
changed to add an additional default subcommand value. For this reason,
add a subcommand value to enable or disable sensors accordingly.

Pull RCU fix from Paul McKenney:
"This fixes a pair of bugs in which an improbable but very real
sequence of events can cause kfree_rcu() to be a bit too quick about
freeing the memory passed to it.
It turns out that this pair of bugs is about two years old, and so
this is not a v6.3 regression. However: (1) It just started showing up
in the wild and (2) Its consequences are dire, so its fix needs to go
in sooner rather than later.
Testing is of course being upgraded, and the upgraded tests detect
this situation very quickly. But to the best of my knowledge right
now, the tests are not particularly urgent and will thus most likely
show up in the v6.5 merge window (the one after this coming one).
Kudos to Ziwei Dai and his group for tracking this one down the hard
way!"

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
blockdev --rereadpt /dev/sdb
mdadm -S /dev/md0
mdadm -A /dev/md0 /dev/sda /dev/sdb
Test result: underlying disk partition and raid partition can be
observed at the same time
Note that this can still happen in come corner cases that
GD_NEED_PART_SCAN can be set for underlying disk while re-assemble raid
device.

Commit c14f7ccc9f5d ("PCI: Assign PCI domain IDs by ida_alloc()")
introduced a use-after-free bug in the bus removal cleanup. The issue was

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:
