sys/dev/mps/mps_sas.c:861:1: error: function 'mpssas_discovery_timeout' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration]
  mpssas_discovery_timeout(void *data)

Because the driver is obtained from upstream, we don't want to modify
it; just silence the warning instead, it is harmless.
