Pull networking fixes from Paolo Abeni:
"Including fixes from can and xfrm.
The TI regression notified last week is actually on our net-next tree,
it does not affect 6.16.
We are investigating a virtio regression which is quite hard to
reproduce - currently only our CI sporadically hits it. Hopefully it
should not be critical, and I'm not sure that an additional week would
be enough to solve it.
Current release - fix to a fix:
- sched: sch_qfq: avoid sleeping in atomic context in qfq_delete_class
Previous releases - regressions:
- xfrm:
- set transport header to fix UDP GRO handling
- delete x->tunnel as we delete x
- eth:
- mlx5: fix memory leak in cmd_exec()
- i40e: when removing VF MAC filters, avoid losing PF-set MAC
- gve: fix stuck TX queue for DQ queue format
Previous releases - always broken:
- can: fix NULL pointer deref of struct can_priv::do_set_mode
- eth:
- ice: fix a null pointer dereference in ice_copy_and_init_pkg()
- ism: fix concurrency management in ism_cmd()
- dpaa2: fix device reference count leak in MAC endpoint handling
- icssg-prueth: fix buffer allocation for ICSSG
Misc:
- selftests: mptcp: increase code coverage"

The Renesas RZ/V2H(P) RSPI IP supports 4-wire and 3-wire
serial communications in both host role and target role.
It can use a DMA, but the I/O can also be driven by the
processor.
RX-only, TX-only, and RX-TX operations are available in
DMA mode, while in processor I/O mode it only RX-TX
operations are supported.
Add a driver to support 4-wire serial communications as
host role in processor I/O mode.

Introduced support for the new SPI IP (SPISG) driver. The SPISG is
a communication-oriented SPI controller from Amlogic,supporting
three operation modes: PIO, block DMA, and scatter-gather DMA.
Due to there is no FIFO, PIO mode can only transfer one word at
a time, which is extremely slow. Therefore, this mode was not
implemented.

SG2044 and SG2042 have similar SPI-NOR flash controller design,
but have incompatibility which causes existing driver
not working on SG2042:
1. SPI-NOR flash controller on SG2042 have no OPT register.
2. FIFO trigger level on SG2042 should be strictly less than 8.
So introduce a new configurable chip_info structure to hold the
different configuration.

Originally an explicit ID for the AXP313/AXP323 regulator was set to
avoid a conflict with the primary AXP717 PMIC on Allwinner A523 family
boards.
This didn't entirely work since on some or all of these boards, the
interrupt line on this secondary PMIC was left unconnected, and thus
the driver would fall back to the generic "no interrupt; only regulators"
case, which didn't have the explicit ID set, thus undoing the intended
fix.
Also set an explicit ID for the regulator cell in the no IRQ generic
fall back case. This fixes the conflict for the AXP717 + AXP313/AXP323
case. For the actual single PMIC with no IRQ connected case, the ID does
not affect functionality, only the device naming of the regulator cell,
and by extension the name and path under sysfs.

The RK806 PMIC has a bitfield for configuring the restart/reset behavior
(which I assume Rockchip calls "function") whenever the PMIC is reset
either programmatically (c.f. DEV_RST in the datasheet) or via PWRCTRL
or RESETB pins.
For RK806, the following values are possible for RST_FUN:
0b00 means "Restart PMU"
0b01 means "Reset all the power off reset registers, forcing
the state to switch to ACTIVE mode"
0b10 means "Reset all the power off reset registers, forcing
the state to switch to ACTIVE mode, and simultaneously
pull down the RESETB PIN for 5mS before releasing"
0b11 means the same as for 0b10 just above.
This adds the appropriate logic in the driver to parse the new
rockchip,reset-mode DT property to pass this information. It just
happens that the values in the binding match the values to write in the
bitfield so no mapping is necessary.
If it is missing, the register is left untouched and relies either on
the silicon default or on whatever was set earlier in the boot stages
(e.g. the bootloader).

On newer boards featuring the A523 SoC, the AXP323 (related to the
AXP313) is paired with the AXP717 and serves as a secondary PMIC
providing additional regulator outputs. However the MFD cells are all
registered with PLATFORM_DEVID_NONE, which causes the regulator cells
to conflict with each other.
Commit e37ec3218870 ("mfd: axp20x: Allow multiple regulators") attempted
to fix this by switching to PLATFORM_DEVID_AUTO so that the device names
would all be different, however that broke IIO channel mapping, which is
also tied to the device names. As a result the change was later reverted.
Instead, here we attempt to make sure the AXP313/AXP323 regulator cell
does not conflict by explicitly giving it an ID number. This was
previously done for the AXP809+AXP806 pair used with the A80 SoC.

The charge-control subsystem in the ChromeOS EC is not strictly tied to
its USB-PD subsystem.
Since commit 7613bc0d116a ("mfd: cros_ec: Don't load charger with UCSI")
the presence of EC_FEATURE_UCSI_PPM would inhibit the probing of the
charge-control driver.
Furthermore recent versions of the EC firmware in Framework laptops
hard-disable EC_FEATURE_USB_PD to avoid probing cros-usbpd-charger,
which then also breaks cros-charge-control.
Instead use the dedicated EC_FEATURE_CHARGER.

Commit 08a149c40bdb ("gpiolib: Clean up headers") added a forward
declaration for struct device.
Later, commit 07445ae1c263 ("gpiolib: of: change of_find_gpio() to
accept device node") changed the function signature to accept a struct
device_node instead of a struct device.
Replace forward declaration of struct device with struct device_node to
match the updated function signature.

irq_domain_create_simple() takes fwnode as the first argument. It can be
extracted from the struct device using dev_fwnode() helper instead of
using of_node with of_fwnode_handle().

In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d2469 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.
Switch to the regular pointer formatting which is safer and
easier to reason about.

When the PSLVERR_RESP_EN parameter is set to 1, the device generates
an error response if an attempt is made to read an empty RBR (Receive
Buffer Register) while the FIFO is enabled.
In serial8250_do_startup(), calling serial_port_out(port, UART_LCR,
UART_LCR_WLEN8) triggers dw8250_check_lcr(), which invokes
dw8250_force_idle() and serial8250_clear_and_reinit_fifos(). The latter
function enables the FIFO via serial_out(p, UART_FCR, p->fcr).
Execution proceeds to the serial_port_in(port, UART_RX).
This satisfies the PSLVERR trigger condition.
When another CPU (e.g., using printk()) is accessing the UART (UART
is busy), the current CPU fails the check (value & ~UART_LCR_SPAR) ==
(lcr & ~UART_LCR_SPAR) in dw8250_check_lcr(), causing it to enter
dw8250_force_idle().
Put serial_port_out(port, UART_LCR, UART_LCR_WLEN8) under the port->lock
to fix this issue.

After a recent change in clang to expose uninitialized warnings from
const variables [1], there is a warning in cxacru_heavy_init():
drivers/usb/atm/cxacru.c:1104:6: error: variable 'bp' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized]
1104 | if (instance->modem_type->boot_rom_patch) {
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/usb/atm/cxacru.c:1113:39: note: uninitialized use occurs here
1113 | cxacru_upload_firmware(instance, fw, bp);
| ^~
drivers/usb/atm/cxacru.c:1104:2: note: remove the 'if' if its condition is always true
1104 | if (instance->modem_type->boot_rom_patch) {
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/usb/atm/cxacru.c:1095:32: note: initialize the variable 'bp' to silence this warning
1095 | const struct firmware *fw, *bp;
| ^
| = NULL
While the warning is technically correct that bp is conditionally passed
uninitialized to cxacru_upload_firmware(), it is ultimately a false
positive warning on the uninitialized use of bp because the same
condition that initializes bp, instance->modem_type->boot_rom_patch, is
the same one that gates the use of bp within cxacru_upload_firmware().
As this warning occurs in clang's frontend before inlining occurs, it
cannot know that these conditions are indentical to avoid the warning.
Manually inline cxacru_upload_firmware() into cxacru_heavy_init(), as
that is its only callsite, so that clang can see that bp is initialized
and used under the same condition, clearing up the warning without any
functional changes to the code (LLVM was already doing this inlining
later).

The macro SET_BITS_TO_LE_2BYTE ends with a semicolon inside its definition,
which can lead to an extra semicolon when used, resulting in inconsistent
formatting or potential warnings.
This patch removes the redundant semicolon to comply with kernel macro
