In particular, it should mention /what/ was changed. Then the commit message would provide more information about /why/ it was changed, and perhaps how it came to be discovered. For example: net: ethernet: stmmac: drop unused variable in stm32mp1_set_mode() Building with W=1 (cf. scripts/Makefile.extrawarn) outputs: warning: variable 'ret' set but not used [-Wunused-but-set-variable] Drop the unused 'ret' variable. > drivers/net/ethernet/stmicro/stmmac/dwmac-stm32.c | 6 +++--- > 1 file changed, 3 insertions(+), 3 deletions(-) > > diff --git a/drivers/net/ethernet/stmicro/stmmac/dwmac-stm32.c b/drivers/net/ethernet/stmicro/stmmac/dwmac-stm32.c > index 4ef041bdf6a1..595af2ec89fb 100644 > --- a/drivers/net/ethernet/stmicro/stmmac/dwmac-stm32.c > +++ b/drivers/net/ethernet/stmicro/stmmac/dwmac-stm32.c > @@ -175,7 +175,7 @@ static int stm32mp1_set_mode(struct plat_stmmacenet_data *plat_dat) > { > struct stm32_dwmac *dwmac = plat_dat->bsp_priv; > u32 reg = dwmac->mode_reg; > - int val, ret; > + int val; > > switch (plat_dat->interface) { > case PHY_INTERFACE_MODE_MII: > @@ -211,8 +211,8 @@ static int stm32mp1_set_mode(struct plat_stmmacenet_data *plat_dat) > } > > /* Need to update PMCCLRR (clear register) */ > - ret = regmap_write(dwmac->regmap, reg + SYSCFG_PMCCLRR_OFFSET, > - dwmac->ops->syscfg_eth_mask); > + regmap_write(dwmac->regmap, reg + SYSCFG_PMCCLRR_OFFSET, > + dwmac->ops->syscfg_eth_mask); > > /* Update PMCSETR (set register) */ > return regmap_update_bits(dwmac->regmap, reg,
