Merge tag 'driver-core-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH: "Here is the set of changes for the driver core for 5.17-rc1. Lots of little things here, including: - kobj_type cleanups - auxiliary_bus documentation updates - auxiliary_device conversions for some drivers (relevant subsystems all have provided acks for these) - kernfs lock contention reduction for some workloads - other tiny cleanups and changes. All of these have been in linux-next for a while with no reported issues" * tag 'driver-core-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (43 commits) kobject documentation: remove default_attrs information drivers/firmware: Add missing platform_device_put() in sysfb_create_simplefb debugfs: lockdown: Allow reading debugfs files that are not world readable driver core: Make bus notifiers in right order in really_probe() driver core: Move driver_sysfs_remove() after driver_sysfs_add() firmware: edd: remove empty default_attrs array firmware: dmi-sysfs: use default_groups in kobj_type qemu_fw_cfg: use default_groups in kobj_type firmware: memmap: use default_groups in kobj_type sh: sq: use default_groups in kobj_type headers/uninline: Uninline single-use function: kobject_has_children() devtmpfs: mount with noexec and nosuid driver core: Simplify async probe test code by using ktime_ms_delta() nilfs2: use default_groups in kobj_type kobject: remove kset from struct kset_uevent_ops callbacks driver core: make kobj_type constant. driver core: platform: document registration-failure requirement vdpa/mlx5: Use auxiliary_device driver data helpers net/mlx5e: Use auxiliary_device driver data helpers soundwire: intel: Use auxiliary_device driver data helpers ...
