Pull staging driver updates from Greg KH:
 "Here is the big set of staging driver updates for 6.19-rc1.

  Only thing "major" in here is that two subsystems, gpib and vc04 have
  moved out of the staging tree into the "real" portion of the kernel,
  which is great to see. Other than that, the rest of the changes are
  just tiny coding style cleanups, nothing earth-shattering.

  All of these have been in linux-next for a while with no reported
  problems"

4d38b88fd1 Merge tag 'printk-for-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
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.

706cc5a936 staging: greybus: uart: check return values during probe
Check the return values of send_control() and send_line_coding() during
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.

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

- 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.

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().

79b6761260 staging: rtl8723bs: use ether_addr_copy() for MAC address copying
Replaces multiple memcpy() calls with ether_addr_copy() for copying
MAC/Ethernet addresses in rtl8723bs. This improves readability and
aligns with Linux kernel best practices for handling Ethernet addresses.

Fixes the following checkpatch.pl warning:
"Use ether_addr_copy() instead of memcpy() for Ethernet addresses."

These updates enhance code clarity and maintain consistency with
network driver conventions.

de4cbbdf2d staging: rtl8723bs: remove todo/note and duplicated EFUSE_CTRL macro
The usage of EFUSE_xxx and MSR macros are already in place, so the note
and todo about that can be removed. Also, there was a duplication of the
definition of EFUSE_CTRL macro in two places, keep the one at the .h file.

495df2da69 staging: most: remove broken i2c driver
The MOST I2C driver has been completely broken for five years without
anyone noticing so remove the driver from staging.

Specifically, commit 723de0f917 ("staging: most: remove device from
interface structure") started requiring drivers to set the interface
device pointer before registration, but the I2C driver was never updated
which results in a NULL pointer dereference if anyone ever tries to
probe it.

a4619aadb3 ALSA: cs35l56: Add support for factory calibration
Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:

Until now, all products with an amplifier supported by the cs35l56 driver
have shipped with Microsoft Windows pre-installed. The factory calibration
of speaker protection has therefore been done using the Windows driver.

However, products that ship with a Linux-based distro must be able to
perform the factory calibration procedure from within the Linux-based
environment. This patch series adds that support.

NOTE: unfortunately this is yet another series that is mainly ASoC but
also needs some changes to the HDA driver, and they have build dependencies
on the ASoC code. I suggest taking this all through Mark's tree and we'll
avoid sending any other commits to the HDA driver until it has all landed
in Takashi's tree.

cf9d07738f ASoC: greybus: use snd_kcontrol_chip() instead of snd_soc_kcontrol_component()
We have very similar name functions (A)(B). Both gets component from
snd_kcontrol, but (A) is used in callback functions which is registered
through snd_soc_add_component_controls(), (B) is used through
snd_soc_dapm_new_widgets().

	(A) snd_soc_kcontrol_component()
	(B) snd_soc_dapm_kcontrol_component()

(B) is using very picky way to get component but using it is necessary in
ASoC. But (A) is just wrapper function to snd_kcontrol_chip(), and directly
using it without wrapper is very common way on ALSA.
To reduce confusions of similar function, let's use common way on (A).
