Merge tag 'driver-core-5.11-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 driver core updates for 5.11-rc1 This time there was a lot of different work happening here for some reason: - redo of the fwnode link logic, speeding it up greatly - auxiliary bus added (this was a tag that will be pulled in from other trees/maintainers this merge window as well, as driver subsystems started to rely on it) - platform driver core cleanups on the way to fixing some long-time api updates in future releases - minor fixes and tweaks. All have been in linux-next with no (finally) reported issues. Testing there did helped in shaking issues out a lot :)" * tag 'driver-core-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (39 commits) driver core: platform: don't oops in platform_shutdown() on unbound devices ACPI: Use fwnode_init() to set up fwnode misc: pvpanic: Replace OF headers by mod_devicetable.h misc: pvpanic: Combine ACPI and platform drivers usb: host: sl811: Switch to use platform_get_mem_or_io() vfio: platform: Switch to use platform_get_mem_or_io() driver core: platform: Introduce platform_get_mem_or_io() dyndbg: fix use before null check soc: fix comment for freeing soc_dev_attr driver core: platform: use bus_type functions driver core: platform: change logic implementing platform_driver_probe driver core: platform: reorder functions driver core: make driver_probe_device() static driver core: Fix a couple of typos driver core: Reorder devices on successful probe driver core: Delete pointless parameter in fwnode_operations.add_links driver core: Refactor fw_devlink feature efi: Update implementation of add_links() to create fwnode links of: property: Update implementation of add_links() to create fwnode links driver core: Use device's fwnode to check if it is waiting for suppliers ...
