Merge tag 'driver-core-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core updates from Greg KH:
 "Here are a small set of changes for 6.5-rc1 for some driver core
  changes. Included in here are:

   - device property cleanups to make it easier to write "agnostic"
     drivers when regards to the firmware layer underneath them (DT vs.
     ACPI)

   - debugfs documentation updates

   - devres additions

   - sysfs documentation and changes to handle empty directory creation
     logic better

   - tiny kernfs optimizations

   - other tiny changes

  All of these have been in linux-next for a while with no reported
  problems"

* tag 'driver-core-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core:
  sysfs: Skip empty folders creation
  sysfs: Improve readability by following the kernel coding style
  drivers: fwnode: fix fwnode_irq_get[_byname]()
  ata: ahci_platform: Make code agnostic to OF/ACPI
  device property: Implement device_is_compatible()
  ACPI: Move ACPI_DEVICE_CLASS() to mod_devicetable.h
  base/node: Use 'property' to identify an access parameter
  driver core: device.h: add some missing kerneldocs
  kernfs: fix missing kernfs_idr_lock to remove an ID from the IDR
  isa: Remove unnecessary checks
  MAINTAINERS: add entry for auxiliary bus
  debugfs: Correct the 'debugfs_create_str' docs
  serial: qcom_geni: Comment use of devm_krealloc rather than devm_krealloc_array
  iio: adc: Use devm_krealloc_array
  hwmon: pmbus: Use devm_krealloc_array
