[ Upstream commit 20054597f169090109fc3f0dfa1a48583f4178a4 ]
Clang warns when one enumerated type is implicitly converted to another.
drivers/scsi/iscsi_tcp.c:803:15: warning: implicit conversion from enumeration type 'enum iscsi_host_param' to different enumeration type 'enum iscsi_param' [-Wenum-conversion] &addr, param, buf); ^~~~~ 1 warning generated.
iscsi_conn_get_addr_param handles ISCSI_HOST_PARAM_IPADDRESS just fine so add an explicit cast to iscsi_param to make it clear to Clang that this is expected behavior.
