Pull char/misc fixes/removals from Greg KH:
 "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"
