Merge tag 'driver-core-5.10-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 patches for 5.10-rc1 They include a lot of different things, all related to the driver core and/or some driver logic: - sysfs common write functions to make it easier to audit sysfs attributes - device connection cleanups and fixes - devm helpers for a few functions - NOIO allocations for when devices are being removed - minor cleanups and fixes All have been in linux-next for a while with no reported issues" * tag 'driver-core-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (31 commits) regmap: debugfs: use semicolons rather than commas to separate statements platform/x86: intel_pmc_core: do not create a static struct device drivers core: node: Use a more typical macro definition style for ACCESS_ATTR drivers core: Use sysfs_emit for shared_cpu_map_show and shared_cpu_list_show mm: and drivers core: Convert hugetlb_report_node_meminfo to sysfs_emit drivers core: Miscellaneous changes for sysfs_emit drivers core: Reindent a couple uses around sysfs_emit drivers core: Remove strcat uses around sysfs_emit and neaten drivers core: Use sysfs_emit and sysfs_emit_at for show(device *...) functions sysfs: Add sysfs_emit and sysfs_emit_at to format sysfs output dyndbg: use keyword, arg varnames for query term pairs driver core: force NOIO allocations during unplug platform_device: switch to simpler IDA interface driver core: platform: Document return type of more functions Revert "driver core: Annotate dev_err_probe() with __must_check" Revert "test_firmware: Test platform fw loading on non-EFI systems" iio: adc: xilinx-xadc: use devm_krealloc() hwmon: pmbus: use more devres helpers devres: provide devm_krealloc() syscore: Use pm_pr_dbg() for syscore_{suspend,resume}() ...
