      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"

        to bring the files into parsable format, and have been acked by
        numerous subsystem maintainers and the documentation maintainer. I
