Merge tag 'driver-core-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core changes from Greg KH:
 "Here is the small set of driver core and debugfs updates for 5.14-rc1.

  Included in here are:

   - debugfs api cleanups (touched some drivers)

   - devres updates

   - tiny driver core updates and tweaks

  Nothing major in here at all, and all have been in linux-next for a
  while with no reported issues"

* tag 'driver-core-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (27 commits)
  docs: ABI: testing: sysfs-firmware-memmap: add some memmap types.
  devres: Enable trace events
  devres: No need to call remove_nodes() when there none present
  devres: Use list_for_each_safe_from() in remove_nodes()
  devres: Make locking straight forward in release_nodes()
  kernfs: move revalidate to be near lookup
  drivers/base: Constify static attribute_group structs
  firmware_loader: remove unneeded 'comma' macro
  devcoredump: remove contact information
  driver core: Drop helper devm_platform_ioremap_resource_wc()
  component: Rename 'dev' to 'parent'
  component: Drop 'dev' argument to component_match_realloc()
  device property: Don't check for NULL twice in the loops
  driver core: auxiliary bus: Fix typo in the docs
  drivers/base/node.c: make CACHE_ATTR define static DEVICE_ATTR_RO
  debugfs: remove return value of debugfs_create_ulong()
  debugfs: remove return value of debugfs_create_bool()
  scsi: snic: debugfs: remove local storage of debugfs files
  b43: don't save dentries for debugfs
