no_llseek had been defined to NULL two years ago, in commit 868941b14441
("fs: remove no_llseek")
To quote that commit,
At -rc1 we'll need do a mechanical removal of no_llseek -
git grep -l -w no_llseek | grep -v porting.rst | while read i; do
sed -i '/\<no_llseek\>/d' $i
done
would do it.
Unfortunately, that hadn't been done. Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
.llseek = no_llseek,
so it's obviously safe.

Pull SoC driver updates from Arnd Bergmann:
"The driver updates seem larger this time around, with changes is many
of the SoC specific drivers, both the custom drivers/soc ones and the
closely related subsystems (memory, bus, firmware, reset, ...).
The at91 platform gains support for sam9x7 chips in the soc and power
management code. This is the latest variant of one of the oldest still
supported SoC families, using the ARM9 (ARMv5) core.
As usual, the qualcomm snapdragon platform gets a ton of updates in
many of their drivers to add more features and additional SoC support.
Most of these are somewhat firmware related as the platform has a
number of firmware based interfaces to the kernel. A notable addition
here is the inclusion of trace events to two of these drivers.
Herve Codina and Christophe Leroy are now sending updates for
drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC
and Arm specific platforms and has previously been problematic to
maintain. The first update here contains support for newer PowerPC
variants and some cleanups.
The turris mox firmware driver has a number of updates, mostly
cleanups.
The Arm SCMI firmware driver gets a major rework to modularize the
existing code into separately loadable drivers for the various
transports, the addition of custom NXP i.MX9 interfaces and a number
of smaller updates.
The Arm FF-A firmware driver gets a feature update to support the v1.2
version of the specification.
The reset controller drivers have some smaller cleanups and a newly
added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs.
The memory controller drivers get some cleanups and refactoring for
Tegra, TI, Freescale/NXP and a couple more platforms.
Finally there are lots of minor updates to firmware (raspberry pi,
tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra,
amlogic, mediatek) drivers and their DT bindings"

Pull timer updates from Thomas Gleixner:
"Core:
- Overhaul of posix-timers in preparation of removing the workaround
for periodic timers which have signal delivery ignored.
- Remove the historical extra jiffie in msleep()
msleep() adds an extra jiffie to the timeout value to ensure
minimal sleep time. The timer wheel ensures minimal sleep time
since the large rewrite to a non-cascading wheel, but the extra
jiffie in msleep() remained unnoticed. Remove it.
- Make the timer slack handling correct for realtime tasks.
The procfs interface is inconsistent and does neither reflect
reality nor conforms to the man page. Show the correct 0 slack for
real time tasks and enforce it at the core level instead of having
inconsistent individual checks in various timer setup functions.
- The usual set of updates and enhancements all over the place.

- Allow the ACPI PM timer to be turned off during suspend
- No new drivers

The "input-events" LED trigger used to turn on the backlight LEDs had to be rewritten to use led_trigger_register_simple() + led_trigger_event() to fix a serious locking issue. This means it no longer supports using blink_brightness to set a per LED brightness for the trigger and it no longer sets LED_CORE_SUSPENDRESUME. Adjust the MiPad 2 bottom bezel touch buttons LED class device to match: 1. Make LED_FULL the maximum brightness to fix the LED brightness being very low when on. 2. Set flags = LED_CORE_SUSPENDRESUME. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/20240916090255.35548-1-hdegoede@redhat.com
Pull thermal control updates from Rafael Wysocki:
"These mostly continue to rework the thermal core and the thermal zone
driver interface to make the code more straightforward and reduce
bloat
The most significant piece of this work is a change of the code
related to binding cooling devices to thermal zones which, among other
things, replaces two previously existing thermal zone operations with
one allowing driver implementations to be much simpler
There is also a new thermal core testing module allowing mock thermal
zones to be created and controlled via debugfs in order to exercise
the thermal core functionality. It is expected to be used for
implementing thermal core self tests in the future
Apart from the above, there are assorted thermal driver updates
Specifics:
- Update some thermal drivers to eliminate thermal_zone_get_trip()
calls from them and get rid of that function (Rafael Wysocki)
- Update the thermal sysfs code to store trip point attributes in
trip descriptors and get to trip points via attribute pointers
(Rafael Wysocki)
- Move the computation of the low and high boundaries for
thermal_zone_set_trips() to __thermal_zone_device_update() (Daniel
Lezcano)
- Introduce a debugfs-based facility for thermal core testing (Rafael
Wysocki)
- Replace the thermal zone .bind() and .unbind() callbacks for
binding cooling devices to thermal zones with one .should_bind()
callback used for deciding whether or not a given cooling devices
should be bound to a given trip point in a given thermal zone
(Rafael Wysocki)
- Eliminate code that has no more users after the other changes, drop
some redundant checks from the thermal core and clean it up (Rafael
Wysocki)
- Fix rounding of delay jiffies in the thermal core (Rafael Wysocki)
- Refuse to accept trip point temperature or hysteresis that would
lead to an invalid threshold value when setting them via sysfs
(Rafael Wysocki)
- Adjust states of all uninitialized instances in the .manage()
callback of the Bang-bang thermal governor (Rafael Wysocki)
- Drop a couple of redundant checks along with the code depending on
them from the thermal core (Rafael Wysocki)
- Rearrange the thermal core to avoid redundant checks and simplify
control flow in a couple of code paths (Rafael Wysocki)
- Add power domain DT bindings for new Amlogic SoCs (Georges Stark)
- Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() in the ST
driver and add a Kconfig dependency on THERMAL_OF subsystem for the
STi driver (Raphael Gallais-Pou)
- Simplify the error code path in the probe functions in the brcmstb
driver with the helo of dev_err_probe() (Yan Zhen)
- Make imx_sc_thermal use dev_err_probe() (Alexander Stein)
- Remove trailing space after \n newline in the Renesas driver (Colin
Ian King)
- Add DT binding compatible string for the SA8255p to the tsens
thermal driver (Nikunj Kela)
- Use the devm_clk_get_enabled() helpers to simplify the init routine
in the sprd thermal driver (Huan Yang)
- Remove __maybe_unused notations for the functions by using the new
RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() macros on the IMx and
Qoriq drivers (Fabio Estevam)
- Remove unused declarations from the ti-soc-thermal driver's header
file as the functions in question were removed previously (Zhang
Zekun)"
