Subject: [PATCH 0/2] crypto/ccp: Properly NULL variables on sev exit             

Stale pointers left in static variables misc_dev and sp_dev_master will
trigger use-after-free error when DEBUG_TEST_DRIVER_REMOVE is configured.
                                                                                 
John Allen (2):
  crypto/ccp: Cleanup misc_dev on sev exit
  crypto/ccp: Cleanup sp_dev_master on psp device destroy
