Hello Jie Yang, The patch 43250ddd75a3: "atl1c: Atheros L1C Gigabit Ethernet driver" from Feb 18, 2009, leads to the following Smatch warning: "drivers/net/ethernet/atheros/atl1c/atl1c_hw.c:472 atl1c_phy_setup_adv() warn: odd binop '0x300 & 0xfffffffffffffcff'" [ This check as too many false positives so I haven't released it ] drivers/net/ethernet/atheros/atl1c/atl1c_hw.c 472 u16 mii_giga_ctrl_data = GIGA_CR_1000T_DEFAULT_CAP & 473 ~GIGA_CR_1000T_SPEED_MASK; The defines are set up like this: #define GIGA_CR_1000T_SPEED_MASK 0x0300 #define GIGA_CR_1000T_DEFAULT_CAP 0x0300 So we're just setting mii_giga_ctrl_data to zero. It seems odd. Did you intend to do the bitwise negate of GIGA_CR_1000T_SPEED_MASK? They're only used one time so I can't tell from the context what was intented. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
