charset="utf-8" Coverity reports a possible buffer overrun due to a non-NUL-terminated string in scsi_property_set_loadparm(). While things are not so easy, because qdev_prop_sanitize_s390x_loadparm is designed to operate on a buffer that is not NUL-terminated, in this case the string *does* have to be NUL-terminated because it is read by scsi_property_get_loadparm and s390_build_iplb.
