   1 From: Gerald Schaefer <geraldsc@de.ibm.com>
   2 Subject: zfcp: fix erp timeout cleanup for port open requests
   3 References: bnc#450096
   4
   5 Symptom:     kernel panic on manylinux idle guests
   6 Problem:     If an open port fsf request times out (in erp) the
   7              corresponding erp_action member of the fsf
   8              request need to set to NULL. If the port structure
   9              will be removed later-on there will be still a
  10              reference in the fsf request to the non existing
  11              erp_action otherwise.
  12 Solution:    setting erp_action to NULL
