After revisit the OPP part of the code I found that OPP pmdomain
is detached with direct call to dev_pm_domain_detach instead of
OPP wraper for detaching pmdomains with OPP table. Correct this
by calling the OPP dev_pm_opp_detach_genpd.

 "Here's some small fixes for 5.10-rc2 and a big driver removal.

  The fixes are for some reported issues in the interconnect and
  coresight drivers, nothing major.

  The "big" driver removal is the MIC drivers have been asked to be
  removed as the hardware never shipped and Intel no longer wants to
  maintain something that no one can use. This is welcomed by many as
  the DMA usage of these drivers was "interesting" and the security
  people were starting to question some issues that were starting to be
  found in the codebase.

  Note, one of the subsystems for this driver, the "VOP" code, will
  probably come back in future kernel versions as it was looking to
  potentially solve some PCIe virtualization issues that a number of
  other vendors were wanting to solve. But as-is, this codebase didn't
  work for anyone else so no actual functionality is being removed.

  All of these have been in linux-next with no reported issues"

Pull driver core and documentation fixes from Greg KH:
 "Here is one tiny debugfs change to fix up an API where the last user
  was successfully fixed up in 5.10-rc1 (so it couldn't be merged
  earlier), and a much larger Documentation/ABI/ update to the files so
  they can be automatically parsed by our tools.

  The Documentation/ABI/ updates are just formatting issues, small ones
  to bring the files into parsable format, and have been acked by
  numerous subsystem maintainers and the documentation maintainer. I
  figured it was good to get this into 5.10-rc2 to help wih the merge
  issues that would arise if these were to stick in linux-next until
  5.11-rc1.

  The debugfs change has been in linux-next for a long time, and the
  Documentation updates only for the last linux-next release"
