Merge tag 'driver-core-7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core

Pull driver core updates from Danilo Krummrich:
 "Core:

   - Add TAINT_FORCED_BIND to taint the kernel and driver module before
     manual sysfs bind/unbind operations; make add_taint_module()
     available to driver core and update taint decoding tools and
     documentation

   - Constify device_show/store_*() attribute parameters and adapt x86
     MCE and perf users to prepare for const dev_ext_attribute instances

   - Fix UAF in NUMA access node registration failure handling by
     dropping the device reference with put_device() instead of directly
     freeing the node

  debugfs:

   - Make debugfs_create_str() read-only to eliminate double-free races
     between concurrent writers; reject writable modes; convert
     interconnect and SoundWire users to local file operations with
     mutex-protected strings

  kobject:

   - Fix out-of-bounds access in kobject_action_type() when parsing
     action strings containing embedded NUL bytes

   - Fix the kobject_set_name() reference in kset_register() kernel-doc

  Rust:

   - DMA:

      - Tie Coherent, CoherentBox and CoherentHandle to the device's
        bound lifetime to prevent retaining DMA allocations beyond
        driver unbind; propagate the lifetime through nova-core and the
        DMA sample driver

   - I/O:

      - Require explicit base types for registers and replace relative
        registers with typed subregion projections; reimplement
        register!() as a proc macro, support registers using existing
        types without inline bitfields, and convert nova-core, Tyr and
        the PCI sample; add AsRepr/AsReprMut and transmute helpers with
        deferred size checks for representation conversions

      - Wrap ResourceSize in a transparent newtype with explicit
        conversions, including checked conversion to usize

   - PCI:

      - Add typed PCIe extended capability lookup and SR-IOV accessors
        for the First VF Offset and decoded VF BAR addresses and widths,
        keeping raw SR-IOV registers private to preserve PCI core
        ownership of their state

   - scatterlist:

      - Honor the device's maximum segment size as well as the DMA
        mapping limit when constructing SG tables

      - Return u32 from SGEntry::dma_len() to match the C segment length
        type

   - misc:

      - Validate auxiliary DeviceId name length explicitly to improve
        compile-time diagnostics for oversized device ID table entries

      - Drop unnecessary 'static bounds from debugfs ScopedDir file
        creation methods to support data containing non-'static
        references, including DMA buffers

  Misc:

   - Add Johan Hovold as driver core maintainer

   - Simplify platform_device_alloc() by returning early on allocation
     failure

   - Fix typos in driver core and kernfs comments"
