Merge tag 'driver-core-5.15-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 5.15-rc1. These do change a number of different things across different subsystems, and because of that, there were 2 stable tags created that might have already come into your tree from different pulls that did the following - changed the bus remove callback to return void - sysfs iomem_get_mapping rework Other than those two things, there's only a few small things in here: - kernfs performance improvements for huge numbers of sysfs users at once - tiny api cleanups - other minor changes All of these have been in linux-next for a while with no reported problems, other than the before-mentioned merge issue" * tag 'driver-core-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (33 commits) MAINTAINERS: Add dri-devel for component.[hc] driver core: platform: Remove platform_device_add_properties() ARM: tegra: paz00: Handle device properties with software node API bitmap: extend comment to bitmap_print_bitmask/list_to_buf drivers/base/node.c: use bin_attribute to break the size limitation of cpumap ABI topology: use bin_attribute to break the size limitation of cpumap ABI lib: test_bitmap: add bitmap_print_bitmask/list_to_buf test cases cpumask: introduce cpumap_print_list/bitmask_to_buf to support large bitmask and list sysfs: Rename struct bin_attribute member to f_mapping sysfs: Invoke iomem_get_mapping() from the sysfs open callback debugfs: Return error during {full/open}_proxy_open() on rmmod zorro: Drop useless (and hardly used) .driver member in struct zorro_dev zorro: Simplify remove callback sh: superhyway: Simplify check in remove callback nubus: Simplify check in remove callback nubus: Make struct nubus_driver::remove return void kernfs: dont call d_splice_alias() under kernfs node lock kernfs: use i_lock to protect concurrent inode updates kernfs: switch kernfs to use an rwsem kernfs: use VFS negative dentry caching ...
