Merge tag 'driver-core-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH: "Here is the "big" set of driver core changes for 5.13-rc1. Nothing major, just lots of little core changes and cleanups, notable things are: - finally set 'fw_devlink=on' by default. All reported issues with this have been shaken out over the past 9 months or so, but we will be paying attention to any fallout here in case we need to revert this as the default boot value (symptoms of problems are a simple lack of booting) - fixes found to be needed by fw_devlink=on value in some subsystems (like clock). - delayed work initialization cleanup - driver core cleanups and minor updates - software node cleanups and tweaks - devtmpfs cleanups - minor debugfs cleanups All of these have been in linux-next for a while with no reported issues" * tag 'driver-core-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (53 commits) devm-helpers: Fix devm_delayed_work_autocancel() kerneldoc PM / wakeup: use dev_set_name() directly software node: Allow node addition to already existing device kunit: software node: adhear to KUNIT formatting standard node: fix device cleanups in error handling code kobject_uevent: remove warning in init_uevent_argv() debugfs: Make debugfs_allow RO after init Revert "driver core: platform: Make platform_get_irq_optional() optional" media: ipu3-cio2: Switch to use SOFTWARE_NODE_REFERENCE() software node: Introduce SOFTWARE_NODE_REFERENCE() helper macro software node: Imply kobj_to_swnode() to be no-op software node: Deduplicate code in fwnode_create_software_node() software node: Introduce software_node_alloc()/software_node_free() software node: Free resources explicitly when swnode_register() fails debugfs: drop pointless nul-termination in debugfs_read_file_bool() driver core: add helper for deferred probe reason setting driver core: Improve fw_devlink & deferred_probe_timeout interaction of: property: fw_devlink: Add support for remote-endpoint driver core: platform: Make platform_get_irq_optional() optional driver core: Replace printf() specifier and drop unneeded casting ...
