'status' is used to interact with a hardware register. It might not be safe to remove it entirely. Mark it as __maybe_unused instead. Fixes the following W=1 kernel build warning(s): drivers/net/ethernet/smsc/smc911x.c: In function ‘smc911x_phy_configure’: drivers/net/ethernet/smsc/smc911x.c:882:6: warning: variable ‘status’ set but not used [-Wunused-but-set-variable] drivers/net/ethernet/smsc/smc911x.c: In function ‘smc911x_phy_interrupt’: drivers/net/ethernet/smsc/smc911x.c:976:6: warning: variable ‘status’ set but not used [-Wunused-but-set-variable] drivers/net/ethernet/smsc/smc911x.c: In function ‘smc911x_timeout’: drivers/net/ethernet/smsc/smc911x.c:1251:6: warning: variable ‘status’ set but not used [-Wunused-but-set-variable] Cc: "David S.
