Hi, Static analysis with Coverity has picked up an issue in commit: commit ba44dc04300441b47618f9933bf36e75a280e5fe Author: Sugaya Taichi <sugaya.taichi@xxxxxxxxxxxxx> Date: Mon Apr 15 20:31:40 2019 +0900 serial: Add Milbeaut serial control In function mlb_usio_rx_chars() the u8 status is being bit-wise AND'd with MLB_USIO_SSR_BRK (which is 1UL << 8) and hence the result is always false, which looks incorrect to me. Is this intentional? Colin
