[PATCH net-next] cxgb4: remove set but not used variables 'multitrc, speed'
From: YueHaibing
Date: Sat Nov 24 2018 - 05:36:49 EST
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/net/ethernet/chelsio/cxgb4/t4_hw.c:5883:6:
warning: variable 'multitrc' set but not used [-Wunused-but-set-variable]
drivers/net/ethernet/chelsio/cxgb4/t4_hw.c:8585:32:
warning: variable 'speed' set but not used [-Wunused-but-set-variable]
'multitrc' never used since introduction in
commit 8e3d04fd7d70 ("cxgb4: Add MPS tracing support")
'speed' never used since introduction in
commit c3168cabe1af ("cxgb4/cxgbvf: Handle 32-bit fw port capabilities")
