24c776355f kernel.h: drop hex.h and update all hex.h users
Remove <linux/hex.h> from <linux/kernel.h> and update all users/callers of
hex.h interfaces to directly #include <linux/hex.h> as part of the process
of putting kernel.h on a diet.

Removing hex.h from kernel.h means that 36K C source files don't have to
pay the price of parsing hex.h for the roughly 120 C source files that
need it.

This change has been build-tested with allmodconfig on most ARCHes.  Also,
all users/callers of <linux/hex.h> in the entire source tree have been
updated if needed (if not already #included).

60fb28ca02 staging: rtl8723bs: core: Use new AES library API
Switch from the old AES library functions (which use struct
crypto_aes_ctx) to the new ones (which use struct aes_enckey).  This
eliminates the unnecessary computation and caching of the decryption
round keys.  The new AES en/decryption functions are also much faster
and use AES instructions when supported by the CPU.

Note that in addition to the change in the key preparation function and
the key struct type itself, the change in the type of the key struct
results in aes_encrypt() (which is temporarily a type-generic macro)
calling the new encryption function rather than the old one.

If firmware authentication failed during driver probe, driver call an
asynchronous API to suspend the psys device but the bus device will be

sure the runtime suspend before disabling its RPM.

ba3588410c host1x: Make remove callback return void
The return value of struct device_driver::remove is ignored by the core
(see device_remove() in drivers/base/dd.c). So it doesn't make sense to
let the host1x remove callback return an int just to ignore it later.

So make the callback return void. All current implementors return 0, so
they are easily converted.

tegra20_vip_soc is shared across translation units but is currently
declared via an extern in vip.c. Move the declaration to vip.h so users get
it via the header and we avoid extern declarations in .c files, matching
the pattern already used by tegra20_vi_soc and tegra210_vi_soc.

43e5302d22 media: tegra-video: Fix memory leak in __tegra_channel_try_format()
The state object allocated by __v4l2_subdev_state_alloc() must be freed
with __v4l2_subdev_state_free() when it is no longer needed.

In __tegra_channel_try_format(), two error paths return directly after
v4l2_subdev_call() fails, without freeing the allocated 'sd_state'
object. This violates the requirement and causes a memory leak.

Fix this by introducing a cleanup label and using goto statements in the
error paths to ensure that __v4l2_subdev_state_free() is always called
before the function returns.

Fixes: 56f64b8235 ("media: tegra-video: Use zero crop settings if subdev has no get_selection")
Fixes: 1ebaeb0983 ("media: tegra-video: Add support for external sensor capture")

Pull printk updates from Petr Mladek:

 - Allow creaing nbcon console drivers with an unsafe write_atomic()
   callback that can only be called by the final nbcon_atomic_flush_unsafe().
   Otherwise, the driver would rely on the kthread.

   It is going to be used as the-best-effort approach for an
   experimental nbcon netconsole driver, see

     https://lore.kernel.org/r/20251121-nbcon-v1-2-503d17b2b4af@debian.org

   Note that a safe .write_atomic() callback is supposed to work in NMI
   context. But some networking drivers are not safe even in IRQ
   context:

     https://lore.kernel.org/r/oc46gdpmmlly5o44obvmoatfqo5bhpgv7pabpvb6sjuqioymcg@gjsma3ghoz35

   In an ideal world, all networking drivers would be fixed first and
   the atomic flush would be blocked only in NMI context. But it brings
   the question how reliable networking drivers are when the system is
   in a bad state. They might block flushing more reliable serial
   consoles which are more suitable for serious debugging anyway.

 - Allow to use the last 4 bytes of the printk ring buffer.

 - Prevent queuing IRQ work and block printk kthreads when consoles are
   suspended. Otherwise, they create non-necessary churn or even block
   the suspend.

 - Release console_lock() between each record in the kthread used for
   legacy consoles on RT. It might significantly speed up the boot.

 - Release nbcon context between each record in the atomic flush. It
   prevents stalls of the related printk kthread after it has lost the
   ownership in the middle of a record

 - Add support for NBCON consoles into KDB

 - Add %ptsP modifier for printing struct timespec64 and use it where
   possible

 - Misc code clean up

502ddcc405 staging: rtl8723bs: fix out-of-bounds read in OnBeacon ESR IE parsing
The Extended Supported Rates (ESR) IE handling in OnBeacon accessed
*(p + 1 + ielen) and *(p + 2 + ielen) without verifying that these
offsets lie within the received frame buffer. A malformed beacon with
an ESR IE positioned at the end of the buffer could cause an
out-of-bounds read, potentially triggering a kernel panic.

Add a boundary check to ensure that the ESR IE body and the subsequent
bytes are within the limits of the frame before attempting to access
them.

This prevents OOB reads caused by malformed beacon frames.

6ef0e1c104 staging: rtl8723bs: fix stack buffer overflow in OnAssocReq IE parsing
The Supported Rates IE length from an incoming Association Request frame
was used directly as the memcpy() length when copying into a fixed-size
16-byte stack buffer (supportRate). A malicious station can advertise an
IE length larger than 16 bytes, causing a stack buffer overflow.

Clamp ie_len to the buffer size before copying the Supported Rates IE,
and correct the bounds check when merging Extended Supported Rates to
prevent a second potential overflow.

This prevents kernel stack corruption triggered by malformed association
requests.

154828bf95 staging: rtl8723bs: fix out-of-bounds read in rtw_get_ie() parser
The Information Element (IE) parser rtw_get_ie() trusted the length
byte of each IE without validating that the IE body (len bytes after
the 2-byte header) fits inside the remaining frame buffer. A malformed
frame can advertise an IE length larger than the available data, causing
the parser to increment its pointer beyond the buffer end. This results
in out-of-bounds reads or, depending on the pattern, an infinite loop.

Fix by validating that (offset + 2 + len) does not exceed the limit
before accepting the IE or advancing to the next element.

This prevents OOB reads and ensures the parser terminates safely on
malformed frames.

device initialization in gb_uart_probe(). If these operations fail, the
device will be left in an inconsistent state, so propagate the error to
properly fail the probe.

Both functions call gb_operation_sync() which can fail with errors such
as -ENOMEM, -ENODEV, or -ETIMEDOUT. Ignoring these errors means the TTY
device would be registered despite incomplete initialization.

IIO: New device support, features and cleanup for 6.19

The usual bunch of new device support, but also quite a bit of cleanup
of the core and older drivers which is always good to see.

New device support
------------------

adi,ad4080
- Add support for AD4081, AD4083, AD4084, AD4086 and AD4087 ADCs with
  slightly different features to existing supported parts (max CNV clock
  count, resolution etc)
adi,adxl380
- Add support for ADXL318 and ADXL319 which have reduced functionality
  compared to other supported parts, particularly around event detection.
aosong,adp810
- New driver for this differential pressure and temperature sensor.
aspeed,adc
- Add support for the AST2700 SoC ADCs which differ in small ways from
  already supported parts.
bosch,sm330
- New driver for this IMU (accelerometer + gyroscop) with I2C and SPI bus
  support.
invensense,icm45600
- New driver for this family of IMUs with sub drivers for accelerometer
  and gyroscope elements. I2C, I3C and SPI busses all supported.
  * Supports ICM45605, ICM45606, ICM45608, ICM45634, ICM45686, ICM45687,
    ICM45688P, ICM45689.
  * Support basic features and FIFO.
maxim,max14001
- New driver for the MAX14001 and MAX14002 ADCs.
renesas,rzt2h
- New driver supporting the RZ/T2H and RZ/N2H ADCs found in various SoCs.
renesas,rznl
- New driver supporting the RZ/NL ADC found in various SoCs.

Features
--------

adi,ad5446
- Add a DT binding doc for the 29 variants currently covered by the driver.
- Add adi,ad5542 which is compatiable with the adi,ad5542a which was
  already supported.
bosch,bma220
- I2C support including an I2C bus watchdog.
- Power supply control
- Data ready trigger.
- Low pass filter control.
- Debugfs register access.
- Add Petre Rodan as a maintainer of this driver (thanks!)
bosch,bmi270
- Add support for motion events.
fsl,mpl3115
- Add a dataready trigger and related sampling frequency control.
- Add threshold events.
infineon,dps310
- Add a specific device tree binding.
maxim,max30100
- Allow control of LED pulse-width in dt-binding. Optimum value depends
  on physical characteristics of the device which contains this sensor.
mediatek,mt2701
- Add dt compatible for the mt8189.
rockchip,saradc
- Add rk3506 compatible which is functionally the same as the already
  supported rk3528 (which is therefore the fallback)
st,lsm6dsx
- Make sampling more flexible when both fifo and events are of interest
  by decoupling the FIFO fill rate from actual sampling.

Cleanup and minor fixes
-----------------------

core
- Document and add might_sleep() to iio_push_to_buffers_with_ts_unaligned()
  as it allocates a buffer, typically just on 1st call.
- Add documentation for iio_push_to_buffers_with_ts() which is being used
  to replace iio_push_to_buffers_with_timestamp() in new code as it
  validates the buffer size.  Make the deprecation of the old function
  clear.
- Document that the store_to() callback in struct iio_buffer_access_funcs
  may be called from contexts that cannot sleep.
- Document that the cb() provided to a callback buffer may be called
  from contexts that cannot sleep.
- Cleanup up industrialio-backend.c comments.
- Call mutex_destroy() in cleanup of buffers.
- Call device_initialize() later to avoid having to call device_put()
  before configuration is otherwise complete.
- Use mutex_init_with_key() to replace opencoded version.
- Use dma_buf_unmap_attachment_unlocked() to replace opencoded version.
- Reorder Makefile for pressure sensors.
various
- Uses sysfs_emit() to replace sprintf() in read_label() and other
  callbacks that typically are used to write data to sysfs buffers.
- Switch to REGCACHE_MAPLE in various drivers.
adi,docs
- Fix up formatting of cross references and other kernel-doc issues.
adi,ad4080
- Fix wrong masking of product IDs.
adi,ad5446
- Use DMA safe buffers as needed for SPI.
- Drop a duplicate device chip specific data structure where two parts
  are functionally identical.
- Fail probe if reference is not available.
- Split up the massive array of chip type specific structures into
  separate structures as this tends to be easier to read and maintain.
- Add explicit of_device_id entries for all supported parts.
- Split I2C and SPI parts away from core to avoid ifdef complexity.
- Switch to devm_mutex_init().
- Make use of guard() to simplify code.
- Applying IWYU principles and reorder headers.
- Various other minor cleanup.
adi,ad7124
- Add debugfs to support single cycle mode, typically only used for cases
  such as validate performance of the ADC.
- Various other minor cleanup including removing some layers of indirection
  that weren't necessary.
- Add extended attributes to the temperature channel which follows the same
  signal path as other channels.
- Replace the setup register allocation strategy with a simpler more
  predictable one (a fix for OOB from this code follows later in this pull
  request).
adi,adxl345
- Ensure dt-binding allows for both interrupt wired at the same time.
arm,scmi
- Replace const_ilog2() with the resulting value which ends up simpler
  to read.
bosch,bma220
- Add correct SPI mode specification to the device tree binding.
- Fix up interrupt type in dt binding example to match that the driver
  expects.
- Relax hard constraint on matching chip ID with a message only so as to
  enable fallback DT compatibles to work.
- Use local struct device *dev to replaces lots of indirect look ups.
- Improve includes on approximate IWYU basis.
- Explicit of_match_table.
- Reset some registers during probe.
- Move to regmap.
- Ensure a timestamp is available when filling the buffer by using a
  locally acquired one rather than relying on trigger top half running.
- Add a utility function to search value pair tables for a match.
- Various other minor improvements.
- Move code to avoid a false dependency of the core code on the I2C module.
bosch,bma400
- Improve register and field naming + organization. Use with FIELD_GET()
  and FIELD_PREP() to allow dropping of shift defines.
- Use macros to define event related fields.
- Switch to an address lookup based on an index variable to replace lots of
  very similar register macros.
- Rename activity_event_en() to generic_event_en() to better reflect what
  it does.
- Improve comments around interrupt register handling.
fsl,mpl3115
- Factor out code for triggered buffer data collection.
- Use more consistent register field naming style.
- Use get_unaligned_be24() to get the pressure.
invensense,mpu6050
- Drop false requirement in DT binding for the interrupt. The driver will
  be able to do less if one is not provided, but some features are still
  available.
invensense,icm45600_i3c
- Fix missing return on failure to match part.
linear,ltc2688
- Use devm_mutex_init() so mutex_destroy() is called in tear down path.
- Use guard() to simplify lock handling in error return paths.
qcom,vadc
- Fix up some kernel-doc related warnings.
rohm,bd79112 and bd79124
- Use regmap_reg_range() helper to set the ranges.
st,lsm6dsx
- Fix units of ODR in structure documentation.
ti,am335x
- Add range checks to avoid a compiler warning.
ti,pac1934
- Switch to system_percpu_wq.

Various other minor typo fixes etc.

2c715c9de2 media: atomisp: gc2235: Fix namespace collision and startup() section placement with -ffunction-sections
When compiled with -ffunction-sections (e.g., for LTO, livepatch, dead
code elimination, AutoFDO, or Propeller), the startup() function gets
compiled into the .text.startup section (or in some cases
.text.startup.constprop.0 or .text.startup.isra.0).

However, the .text.startup and .text.startup.* sections are also used by
the compiler for __attribute__((constructor)) code.

This naming conflict causes the vmlinux linker script to wrongly place
startup() function code in .init.text, which gets freed during boot.

Some builds have a mix of objects, both with and without
-ffunctions-sections, so it's not possible for the linker script to
disambiguate with #ifdef CONFIG_FUNCTION_SECTIONS or similar.  This
means that "startup" unfortunately needs to be prohibited as a function
name.

Rename startup() to gc2235_startup().

can even be cloned into .text.startup.constprop.0 or
