We found a NULL pointer dereference in iscsi_sw_tcp_conn_get_param(), the root reason is we did sysfs addition wrong.
iscsi_create_conn() expose iscsi_cls_conn to sysfs while the related resources are not initialized. So we should delay the calling of device_add() until these resources has been initialized. This patchset solve this issue by changing iscsi_conn_setup() and works well for iscsi_tcp.
