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
