Subject: [GIT PULL] Driver core changes for 6.18-rc1
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).
- Danilo

rust: pci: display symbolic PCI vendor names (2025-09-25 15:52:00 +0200)
----------------------------------------------------------------
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
