  VMCI: Fix process-to-process DRGAMs.
  mei: ME hardware reset needs to be synchronized
  mei: add mei_stop function to stop mei device
  extcon: max77693: Initialize register of MUIC device to bring up it without platform data
  extcon: max77693: Fix bug of wrong pointer when platform data is not used
  extcon: max8997: Check the pointer of platform data to protect null pointer error
