Merge tag 'driver-core-6.6-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core fixes from Greg KH:
 "Here is a single driver core fix for a much-reported-by-sysbot issue
  that showed up in 6.6-rc1. It's been submitted by many people, all in
  the same way, so it obviously fixes things for them all.

  Also in here is a single documentation update adding riscv to the
  embargoed hardware document in case there are any future issues with
  that processor family.

  Both of these have been in linux-next with no reported problems"
