Dan Carpenter 8ca0e780b4 media: cec: silence shift wrapping warning in __cec_s_log_addrs() ... [ Upstream commit 3b5af3171e ] The log_addrs->log_addr_type[i] value is a u8 which is controlled by the user and comes from the ioctl. If it's over 31 then that results in undefined behavior (shift wrapping) and that leads to a Smatch static checker warning. We already cap the value later so we can silence the warning just by re-ordering the existing checks. I think the UBSan checker will also catch this bug at runtime and generate a warning. But otherwise the bug is harmless.
