TIOCGSERIAL is an ioctl. Thus it must be atomic. It returns
two values. Racing with set_serial it can return an inconsistent
result. The mutex must be taken.
In terms of logic the bug is as old as the driver. In terms of
code it goes back to the conversion to the get_serial and
set_serial methods.

If the busy indicator is set, all other fields in CCI should be
clear according to the spec. However, some UCSI implementations do
not follow this rule and report bogus data in CCI along with the
busy indicator. Ignore the contents of CCI if the busy indicator is
set.
If a command timeout is hit it is possible that the EVENT_PENDING
bit is cleared while connector work is still scheduled which can
cause the EVENT_PENDING bit to go out of sync with scheduled connector
work. Check and set the EVENT_PENDING bit on entry to
ucsi_handle_connector_change() to fix this.
Finally, check UCSI_CCI_BUSY before the return code of ->sync_control.
This ensures that the command is cancelled even if ->sync_control
returns an error (most likely -ETIMEDOUT).

The __get_dwc3_maximum_speed() function returns an enum type which, in
this context here, is basically unsigned int. On error cases, it's
supposed to return USB_SPEED_UNKNOWN, but it was accidentally changed to
return negative error codes in commit f93e96c544 ("usb: dwc3: rtk: use
scoped device node handling to simplify error paths").
There is only one caller and because of the way that the types work out,
returning negative error codes is not a problem. They will be treated
as greater than USB_SPEED_HIGH and ignored as invalid. So this patch
does not affect run time behavior, it's just a clean up.

Improve commit fc88bb1161 ("usb: roles: add lockdep class key to struct
usb_role_switch") as follows:
* Move the lock class key declaration just above the mutex declaration such
that the declaration order of these objects matches their initialization
order.
* Destroy the mutex and lock class key just before these objects are
freed. This makes it easier to verify that the destruction calls happen
after the last use of these objects.
* Instead of switching the mutex key to the dynamic lock class key after
initialization of the mutex has completed, initialize the mutex with the
dynamic lock class key.

With CONFIG_PREEMPT_RT disabled __mutex_init() is a function. With
CONFIG_PREEMPT_RT enabled, __mutex_init() is a macro. I assume this is why
mutex_init() is defined twice as exactly the same macro.
Prepare for introducing a new macro for mutex initialization by combining
the two identical mutex_init() definitions into a single definition. This
patch does not change any functionality because the C preprocessor expands
macros when it encounters the macro name and not when a macro definition
is encountered. See also commit bb630f9f7a ("locking/rtmutex: Add mutex

Streams should flush their TRB cache, re-read TRBs, and start executing
TRBs from the beginning of the new dequeue pointer after a 'Set TR Dequeue
Pointer' command.
Cadence controllers may fail to start from the beginning of the dequeue
TRB as it doesn't clear the Opaque 'RsvdO' field of the stream context
during 'Set TR Dequeue' command. This stream context area is where xHC
stores information about the last partially executed TD when a stream
is stopped. xHC uses this information to resume the transfer where it left
mid TD, when the stream is restarted.
Patch fixes this by clearing out all RsvdO fields before initializing new
Stream transfer using a 'Set TR Dequeue Pointer' command.

usb5744 supports SMBus Configuration and it may be configured via the
SMBus slave interface during the hub start-up configuration stage.
To program it driver uses i2c-bus phandle (added in commit '02be19e914b8
dt-bindings: usb: Add support for Microchip usb5744 hub controller') to
get i2c client device and then based on usb5744 compatible check calls
usb5744 i2c default initialization sequence.
Apart from the USB command attach, prevent the hub from suspend.
when the USB Attach with SMBus (0xAA56) command is issued to the hub,
the hub is getting enumerated and then it puts in a suspend mode.
This causes the hub to NAK any SMBus access made by the SMBus Master
during this period and not able to see the hub's slave address while
running the "i2c probe" command.
Prevent the MCU from putting the HUB in suspend mode through register
write. The BYPASS_UDC_SUSPEND bit (Bit 3) of the RuntimeFlags2
register at address 0x411D controls this aspect of the hub. The
BYPASS_UDC_SUSPEND bit in register 0x411Dh must be set to ensure that the
MCU is always enabled and ready to respond to SMBus runtime commands.
This register needs to be written before the USB attach command is issued.
The byte sequence is as follows:
Slave addr: 0x2d 00 00 05 00 01 41 1D 08
Slave addr: 0x2d 99 37 00
Slave addr: 0x2d AA 56 00
Also since usb5744 i2c initialization routine uses i2c SMBus APIs invoke
these APIs only when i2c driver is enabled in the kernel configuration.

Introduce dedicated field 'power_on_delay_us' in onboard platform data
and update its delay for USB5744 configuration. Hub itself requires some
delay after reset to get to state where configuration data is going to
be accepted. Without delay upcoming support for configuration via SMBUS
is reporting a failure on the first SMBus write.
i2c 2-002d: error -ENXIO: BYPASS_UDC_SUSPEND bit configuration failed
Similar delay is likely also required for default configuration but
because there is enough time (code execution) between reset and usage
of the hub any issue is not visible but it doesn't mean delay shouldn't
be reflected.

peripheral mode when no other power-down mode is available (introduced by
commit 0112b7ce68 ("usb: dwc2: Update dwc2_handle_usb_suspend_intr function.")).
However, the dwc2_drd_role_sw_set() USB role update handler attempts to
read DWC2 registers if the USB role has changed while the USB is in suspend
mode (when the clocks are gated). This causes the system to hang.
Release the gadget clocks before handling the USB role update.

TCPCI USB PHY - PTN5110 could be used with SOCs that only support
the edge-triggered GPIO interrupts such as TI's K3 device AM69.
Move the interrupt configuration to the firmware which would
allow to accommodate edge triggered interrupts for such SOCs.
In order to support the edge interrupts, register irq line in advance
and keep track of occurrence during port registering.
When the edge interrupts are used, it is observed that some of the
interrupts are missed when tcpci_irq() is serving the current
interrupt. Therefore, check the status register at the end of
tcpci_irq() and re-run the function if the status is not clear
i.e. pending interrupt.

There are a handful of patches here that fix masks and skip
enabling the clk from set_rate() when the PLL is disabled. The PLLs
are crucial to operation of the system as almost all frequencies in
the system are derived from them.
- Parking shared RCGs at a slow always on clk at registration time
breaks stuff.
USB host mode can't handle such a slow frequency and the serial
console gets all garbled when the UART clk is handed over to the
kernel. There's a few patches that don't use the shared clk_ops for
the UART clks and another one to skip parking the USB clk at
registration time.
- The Starfive PLL driver used for the CPU was busted causing cpufreq
to fail because the clk didn't change to a safe parent during
set_rate().
The fix is to register a notifier and switch to a safe parent so

Pull x86 kvm fixes from Paolo Bonzini:
"Many small fixes that accumulated while I was on vacation...
- Fixup missed comments from the REMOVED_SPTE => FROZEN_SPTE rename
- Ensure a root is successfully loaded when pre-faulting SPTEs
- Grab kvm->srcu when handling KVM_SET_VCPU_EVENTS to guard against
accessing memslots if toggling SMM happens to force a VM-Exit
- Emulate MSR_{FS,GS}_BASE on SVM even though interception is always
disabled, so that KVM does the right thing if KVM's emulator
encounters {RD,WR}MSR
- Explicitly clear BUS_LOCK_DETECT from KVM's caps on AMD, as KVM
doesn't yet virtualize BUS_LOCK_DETECT on AMD
- Cleanup the help message for CONFIG_KVM_AMD_SEV, and call out that
KVM now supports SEV-SNP too
- Specialize return value of
KVM_CHECK_EXTENSION(KVM_CAP_READONLY_MEM), based on VM type
- Remove unnecessary dependency on CONFIG_HIGH_RES_TIMERS
- Note an RCU quiescent state on guest exit. This avoids a call to
rcu_core() if there was a grace period request while guest was
running"

Pull block fixes from Jens Axboe:
"Mostly just some fixlets for NVMe, but also a bug fix for the ublk
driver and an integrity fix"
* tag 'block-6.11-20240906' of git://git.kernel.dk/linux:
bio-integrity: don't restrict the size of integrity metadata

Pull sound fixes from Takashi Iwai:
"Hopefully the last PR for 6.11, at least for this level of amount.
In addition to the usual HD-audio quirks, there are more changes in
ASoC, but all look small and device-specific fixes, and nothing stands
out. The only slightly big change is sunxi I2S fix, which looks quite
safe to apply, too"
