Merge tag 'driver-core-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core

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:
   - Avoid iattr allocation in kernfs listxattr by using
     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.
   - Remove redundant nodemask clears in numa_init().
   - Add kernel-doc for fwnode_operations and sys_soc.h, mark
     internal property data as private for kernel-doc, and add
     property.h/fwnode.h to driver-api infrastructure docs.
   - Add MAINTAINERS entry for sys_soc.h"
