However, that commit failed to cast the pointer to an appropriate type which in this case is a u64. As such sparse warnings are generated for both correlation token assignments. ibmvfc.c:2375:36: sparse: incorrect type in argument 1 (different base types) ibmvfc.c:2375:36: sparse: expected unsigned long long [usertype] val ibmvfc.c:2375:36: sparse: got struct ibmvfc_event *[assigned] evt Add the apporpriate u64 casts when assigning an ibmvfc_event as a correlation token.
