Merge tag 'driver-core-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core

Pull driver core updates from Greg KH:
 "Here are the driver core / kernfs changes for 6.16-rc1.

  Not a huge number of changes this development cycle, here's the
  summary of what is included in here:

   - kernfs locking tweaks, pushing some global locks down into a per-fs
     image lock

   - rust driver core and pci device bindings added for new features.

   - sysfs const work for bin_attributes.

     The final churn of switching away from and removing the
     transitional struct members, "read_new", "write_new" and
     "bin_attrs_new" will come after the merge window to avoid
     unnecesary merge conflicts.

   - auxbus device creation helpers added

   - fauxbus fix for creating sysfs files after the probe completed
     properly

   - other tiny updates for driver core things.

  All of these have been in linux-next for over a week with no reported
  issues"
