This is an experimental semi-automated report about issues detected by Coverity from a scan of next-20221104 as part of the linux-next scan project: https://scan.coverity.com/projects/linux-next-weekly-scan You're getting this email because you were associated with the identified lines of code (noted below) that were touched by commits: Wed Nov 2 12:31:23 2022 +0000 049fe5365324 ("net: txgbe: Add operations to interact with firmware") Coverity reported the following: *** CID 1527152: Control flow issues (NO_EFFECT) drivers/net/ethernet/wangxun/txgbe/txgbe_hw.c:200 in txgbe_calc_eeprom_checksum() 194 195 for (i = 0; i < TXGBE_EEPROM_LAST_WORD; i++) 196 if (i != wxhw->eeprom.sw_region_offset + TXGBE_EEPROM_CHECKSUM) 197 *checksum += local_buffer[i]; 198 199 *checksum = TXGBE_EEPROM_SUM - *checksum; vvv CID 1527152: Control flow issues (NO_EFFECT) vvv This less-than-zero comparison of an unsigned value is never true.
