commit 51cdd69d6a857f527d6d0697a2e1f0fa8bca1005 upstream.
This reverts commit ec6ce7075ef879b91a8710829016005dc8170f17.
Fix installation of WinUSB driver using OS descriptors. Without the
fix the drivers are not installed correctly and the property
'DeviceInterfaceGUID' is missing on host side.
The original change was based on the assumption that the interface
number is in the high byte of wValue but it is in the low byte,
instead. Unfortunately, the fix is based on MS documentation which is
also wrong.
The actual USB request for OS descriptors (using USB analyzer) looks
like:
Offset 0 1 2 3 4 5 6 7
0x000 C1 A1 02 00 05 00 0A 00
C1: bmRequestType (device to host, vendor, interface)
A1: nas magic number
0002: wValue (2: nas interface)
0005: wIndex (5: get extended property i.e. nas interface GUID)
008E: wLength (142)
The fix was tested on Windows 10 and Windows 11.

[ Upstream commit 422dc0a4d12d0b80dd3aab3fe5943f665ba8f041 ]
chaoskey_open() takes the lock only to increase the
counter of openings. That means that the mutual exclusion
with chaoskey_disconnect() cannot prevent an increase
of the counter and chaoskey_open() returning a success.
If that race is hit, chaoskey_disconnect() will happily
free all resources associated with the device after
it has dropped the lock, as it has read the counter
as zero.
To prevent this race chaoskey_open() has to check
the presence of the device under the lock.
However, the current per device lock cannot be used,
because it is a part of the data structure to be
freed. Hence an additional global mutex is needed.
The issue is as old as the driver.

iowarrior_read() uses the iowarrior dev structure, but does not use any
lock on the structure. This can cause various bugs including data-races,
so it is more appropriate to use a mutex lock to safely protect the
iowarrior dev structure. When using a mutex lock, you should split the
branch to prevent blocking when the O_NONBLOCK flag is set.
In addition, it is unnecessary to check for NULL on the iowarrior dev
structure obtained by reading file->private_data. Therefore, it is
better to remove the check.

While design wise the idea of converting the driver to use
the hierarchy of the IRQ chips is correct, the implementation
has (inherited) flaws. This was unveiled when platform_get_irq()
had started WARN() on IRQ 0 that is supposed to be a Linux
IRQ number (also known as vIRQ).
Rework the driver to respect IRQ domain when creating each MFD
device separately, as the domain is not the same for all of them.

[ Upstream commit 4058c39bd176daf11a826802d940d86292a6b02b ]
The issue is that before entering the crash kernel, the DWC USB controller
did not perform operations such as resetting the interrupt mask bits.
After entering the crash kernel,before the USB interrupt handler
registration was completed while loading the DWC USB driver,an GINTSTS_SOF
interrupt was received.This triggered the misroute_irq process within the
GIC handling framework,ultimately leading to the misrouting of the
interrupt,causing it to be handled by the wrong interrupt handler
and resulting in the issue.
Summary:In a scenario where the kernel triggers a panic and enters
the crash kernel,it is necessary to ensure that the interrupt mask
bit is not enabled before the interrupt registration is complete.
If an interrupt reaches the CPU at this moment,it will certainly
not be handled correctly,especially in cases where this interrupt
is reported frequently.
Please refer to the Crashkernel dmesg information as follows
(the message on line 3 was added before devm_request_irq is
called by the dwc2_driver_probe function):

[ Upstream commit e4fdcc10092fb244218013bfe8ff01c55d54e8e4 ]
Currently, suspend interrupt is enabled before pullup enable operation.
This will cause a suspend interrupt assert right after pullup DP. This
suspend interrupt is meaningless, so this will ignore such interrupt
by enable it after usb reset completed.

[ Upstream commit f81dfa3b57c624c56f2bff171c431bc7f5b558f2 ]
PCI xHC host should be stopped and xhci driver memory freed before putting
host to PCI D3 state during PCI remove callback.
Hosts with XHCI_SPURIOUS_WAKEUP quirk did this the wrong way around
and set the host to D3 before calling usb_hcd_pci_remove(dev), which will
access the host to stop it, and then free xhci.
Fixes: f1f6d9a8b540 ("xhci: don't dereference a xhci member after removing xhci")
