cxgb4: fix set but unused variable when DCB is disabled
Remove the set but unused variable when DCB is disabled. Instead, do the calculation directly inline. Fixes following warning in make W=1: cxgb4_main.c: In function 'cfg_queues': cxgb4_main.c:5380:29: warning: variable 'n1g' set but not used [-Wunused-but-set-variable] u32 i, n10g = 0, qidx = 0, n1g = 0; ^ Fixes: 116ca924aea6 ("cxgb4: fix checks for max queues to allocate") Signed-off-by: Rahul Lakkireddy <rahul.lakkireddy@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
