Pull driver core updates from Danilo Krummrich:
 "container_of:

   - Apply typeof_member(), remove the local __mptr variable to

     kunit-managed fwnode helpers and test coverage

   - Fix infinite loop in fwnode_for_each_child_node() when the
     secondary fwnode has more than one child. Add test cases

   - Refactor to use RAII approach with __free()

   - Add Bartosz Golaszewski as software node reviewer

  firmware loader:

   - Fix race where a sysfs fallback request can complete before being
     queued as pending, leading to a use-after-free on the next fallback
     request

   - Reject 0-size built-in firmware and fail the build on empty
     firmware files in CONFIG_EXTRA_FIRMWARE

  kobject:

     and platform_device_set_of_node_from_dev() helpers that encapsulate

         coercion to shorter lifetimes

   - Devres:
       - Fix race between concurrent revokers where the losing revoker
         could return before the winning revoker finished dropping the
         inner data, causing use-after-free.
       - Ensure revocation is complete before the device finishes
         unbinding by making the synchronization bidirectional.
       - Add DevresLt<F: ForLt>, a wrapper around Devres that shortens
         'static back to the caller's borrow scope. Implement ForLt and
         CovariantForLt for Bar, IoMem, and ExclusiveIoMem

   - Driver:
       - Switch from index-based to pointer-based device ID info lookup,
         storing static references in driver_data. Centralize device ID
         handling in device_id.rs, removing the open-coded ACPI/OF
         matching logic and duplicate ID table from driver.rs

         for primitives and copying methods for aggregates; drop the old
         macros. Convert nova-core to use I/O projection.
       - Fix internal shortcut rule dispatch in the register!() macro,
         remove unused rule arguments, and use path fragments for alias
         destinations

gpio: legacy interface cleanups for 7.3

These are the remaining patches for legacy gpio interface
cleanup, ensuring that files referencing them are sure to
have CONFIG_GPIOLIB_LEGACY set, and use linux/gpio/legacy.h
instead of the old linux/gpio.h header.

There are a few more patches already merged in other
branches for 7.3, including soc, led, net and media. Once
everything is in, we can apply the final patches to turn
off CONFIG_GPIOLIB_LEGACY by default and remove the obsolete
header file.

This branch is based on the immutable ib-mfd-legacy-gpio-7.3
branch from mfd.git to avoid a conflict in the rohm drivers.

Pull SoC driver updates from Arnd Bergmann:
 "There are a few added drivers, but mostly the normal maintenance to
  drivers for firmware, memory controller and other soc specific
  hardware:

   - The NXP QuickEngine gets modern MSI support, which allows some
     cleanups to the GICv3 irqchip chip driver

   - A new SoC specific driver for the Renesas R-Car MFIS unit is added,
     encapsulating support for the on-chip mailbox and hwspinlock
     implementations that are not easily separated into individual
     drivers

   - The Qualcomm SoC drivers add support for additional SoC
     implementations, and flexibility around power management for the
     serial-engine driver as well as probing the LLCC driver using
     custom hardware descriptions inside of the device itself.

   - Added support for the Samsung thermal management unit

   - A cleanup to the Tegra 'PMC' driver interfaces to remove legacy
     APIs and allow multiple PMC instances everywhere.

   - Updates to the TI SCI and KNAS drivers to improve suspend/resume
     support.

   - Minor driver changes for mediatek, xilinx, allwinner, aspeed,
     tegra, broadcom, amd, microchip and starfive specific drivers

   - Memory controller updates for Tegra and Renesas for additional SoC
     types and other improvements.

   - Firmware driver updates for Arm FF-A, SMCCC and SCMI interfaces, to
     update driver probing, object lifetimes and address minor bugs"
