Pull driver core updates from Danilo Krummrich:
 "container_of:

   - Apply typeof_member(), remove the local __mptr variable to
     eliminate variable shadowing warnings on nested container_of()
     calls, and remove unnecessary parentheses

  core:

   - Add driver name to probe debug print for initcall_debug

   - Avoid repeatedly printing the same 'Fixed dependency cycle' log

   - Unwind device_add() on attribute creation failure in
     attribute_container_add_class_device()

   - Remove statistics group if encryption group creation fails in
     transport_add_class_device()

  debugfs:

   - Fix lockdown check for mmap_prepare()

   - Warn if file creation failed due to uninitialized debugfs

  device property:

   - Implement fw_devlink support for software nodes by adding
     software_node_add_links(), which creates fwnode links from
     DEV_PROP_REF properties to enable automatic probe ordering. Add
     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

   - Fix out-of-bounds access in software_node_get_reference_args() when
     called with index -1 (UINT_MAX)

   - 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:

   - Provide __KOBJ_ATTR() and __KOBJ_ATTR_RO/WO() initialization macros
     and allow the constification of kobject attributes, enabling them
     to reside in read-only memory

  platform:

   - Provide platform_device_set_of_node(), platform_device_set_fwnode(),
     and platform_device_set_of_node_from_dev() helpers that encapsulate
     firmware node reference counting for dynamically allocated platform
     devices

     Convert all in-tree users that manually assigned dev.of_node or
     dev.fwnode, fixing a pre-existing refcount bug in powermac. Switch
     to counting references of all firmware node types, not only OF
     nodes

   - Unify the release path for dynamically allocated platform devices
     by removing platform_device_release_full(). Amend the fwnode setter
     API contract to warn if a primary software node is overwritten. Add
     KUnit tests for correct software node removal on device
     unregistration

  Rust:

   - Auxiliary:
       - Add registration_data_with() closure-based API for invariant
         ForLt types

   - Debugfs:
       - Migrate BinaryWriter and BinaryReaderMut trait requirements
         from kernel::transmute traits to zerocopy traits

   - Device:
       - Add BoundInternal device context and InternalBoundContext trait
         for bus abstractions that need internal access to a bound
         device.
       - Make the lifetime on Core and CoreInternal invariant to prevent
         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

   - I/O:
       - Make I/O regions typed (with a dynamically-sized Region type
         for the existing untyped case), create view types representing
         subregions of a mapped I/O region, and add io_project!() for
         safely creating subviews.
       - Split Io into a base trait (IoBase) and an extension trait (Io)
         with a blanket implementation, preventing implementers from
         overriding provided methods that unsafe code relies on.
       - Add a SysMem backend for shared system memory with volatile
         access, and make Coherent implement Io via an I/O view type.
         Add IoSysMap as sum type of Mmio and SysMem. Add copying
         methods (memcpy_{from,to}io()) and read_val()/write_val() for
         typed access.
       - Replace dma_read!()/dma_write!() with io_read!()/io_write!()
         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

   - IRQ:
       - Make irq::Registration compatible with lifetime-bound drivers
         by removing the 'static bound on Handler/ThreadedHandler and
         replacing Devres<RegistrationInner> with direct
         request_irq()/free_irq() calls. Handlers can now directly own
         lifetime-bound device resources

   - PCI:
       - Convert IrqVectorRegistration to a lifetime-annotated owning
         type, giving drivers explicit control over the allocation
         lifetime. IrqVector embeds a resolved IrqRequest, making the
         conversion infallible. Remove the redundant
         request_irq()/request_threaded_irq() wrappers from pci::Device.
       - Add pci_irq_type() C helper and expose it via irq_type() on
         IrqVectorRegistration and IrqVector, returning PCI_IRQ_MSIX,
         PCI_IRQ_MSI, or PCI_IRQ_INTX.
       - Mark pci::Device refcount methods inline

   - Serdev:
       - Add Rust abstractions for the serial device bus, including
         serdev::Driver trait, serdev::Device wrapping struct
         serdev_device, and serdev::Adapter implementing
         RegistrationOps. Includes a sample driver. Markus Probst takes
         over as serdev maintainer for both C and Rust code

   - Misc:
       - Split ForLt into a base trait (providing the Of<'a> GAT) and an
         unsafe CovariantForLt subtrait guaranteeing covariance,
         enabling invariant types (e.g. those containing Mutex<&'bound T>)
         to participate in the ForLt abstraction.
       - Fix Coherent read past EOF returning -ERANGE instead of zero.
       - Fix firmware example UB by avoiding null-pointer ARef

  misc:

     kernfs_iattrs_noalloc().
   - Unregister SoC bus on early device registration failure.
   - Remove unused DMA_FENCE_TRACE Kconfig symbol.
   - Fix /sys/module path in comment.
   - Refactor ISA bus init to remove nested blocks.

platform/chrome: of_hw_prober: Add delay for hana trackpads

Up until now, the MT8173 elm/hana device tree has set the dedicated
regulator supplying the trackpad as always-on, simply because the Elan
driver was missing proper delays. As a result the delay for the
Synaptics trackpad was also omitted, as it was not strictly required
under such a model and delayed the availability of the trackpad to the
user.

The Elan driver recently gained proper delays after power-up, with
adaptive skipping of the delay if the regulator was originally
on. The I2C HID driver and I2C OF component prober library gained
similar adaptive delay skipping. The device tree will be fixed to have
the regulator not be always on, and proper post-power-on delay time
added to the I2C HID device.

Also add the post-power-on delay to the ChromeOS OF component prober,
so that if the regulator is off at the time of probing, the prober knows
to wait for the hardware to initialize.

Merge updates related to the ACPI video bus driver for 7.3-rc1:

 - Introduce helper function acpi_dev_is_video_device() and use it in
   the core ACPI device enumeration code, in the ACPI video bus driver,
   in the ACPI support code for I2C, in the PCI VGA driver, and in the
   x86 platform thinkpad_acpi driver (Andy Shevchenko)

 - Add a quirk to use the native backlight on Acer Nitro AN515-46 to the
   ACPI video bus driver (Marcos Paulo Medeiros)

 - Release PCI device reference after lookup in video_detect_portege_r100()
   in the ACPI video bus driver (Yuho Choi)
