[GIT PULL] Driver core changes for 6.18-rc1

["Danilo Krummrich" <dakr@kernel.org>]

Hi Linus,

Please pull these driver-core changes.

I did a test merge pulling in Miguel's Rust tree and found two trivial include
conflicts -- otherwise no conflicts expected.

All changes have been in linux-next for at least six rounds (except for two
minor patches that change the Display implementation of pci::Vendor and
pci::Class to print the actual vendor and class name).

Driver core changes for 6.18-rc1

- Auxiliary:
   - Drop call to dev_pm_domain_detach() in auxiliary_bus_probe()
   - Optimize logic of auxiliary_match_id()

- Rust:
  - Auxiliary:
    - Use primitive C types from prelude

  - DebugFs:
    - Add debugfs support for simple read/write files and custom callbacks
      through a File-type-based and directory-scope-based API
    - Sample driver code for the File-type-based API
    - Sample module code for the directory-scope-based API

  - I/O:
    - Add io::poll module and implement Rust specific read_poll_timeout()
      helper

  - IRQ:
    - Implement support for threaded and non-threaded device IRQs based on
      (&Device<Bound>, IRQ number) tuples (IrqRequest)
    - Provide &Device<Bound> cookie in IRQ handlers

  - PCI:
    - Support IRQ requests from IRQ vectors for a specific pci::Device<Bound>
    - Implement accessors for subsystem IDs, revision, devid and resource start
    - Provide dedicated pci::Vendor and pci::Class types for vendor and class
      ID numbers
    - Implement Display to print actual vendor and class names; Debug to print
      the raw ID numbers
    - Add pci::DeviceId::from_class_and_vendor() helper
    - Use primitive C types from prelude
    - Various minor inline and (safety) comment improvements

  - Platform:
    - Support IRQ requests from IRQ vectors for a specific
      platform::Device<Bound>

  - Nova:
    - Use pci::DeviceId::from_class_and_vendor() to avoid probing
      non-display/compute PCI functions

  - Misc:
    - Add helper for cpu_relax()
    - Update ARef import from sync::aref

- sysfs:
  - Remove bin_attrs_new field from struct attribute_group
  - Remove read_new() and write_new() from struct bin_attribute

- Misc:
  - Document potential race condition in get_dev_from_fwnode()
  - Constify node_group argument in software node registration functions
  - Fix order of kernel-doc parameters in various functions
  - Set power.no_pm flag for faux devices
  - Set power.no_callbacks flag along with the power.no_pm flag
  - Constify the pmu_bus bus type
  - Minor spelling fixes
