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
