ERROR:SPACING: space prohibited before that ',' (ctx:WxW)
#84: FILE: lib/librte_distributor/rte_distributor.c:172:
+BIND_DEFAULT_SYMBOL(rte_distributor_get_pkt, , 17.05);
                                               ^

FYI, checkpatch does not like this regardless of whether there's
a space there or not. It complains either way. :)

Regards,
Dave.
