Merges https://github.com/espressif/esp-idf/pull/12093 fix(ll): remove FLAG_ATTR macro Such kind of operator overload will not work because C++ thinks such overload is ambiguous and it still prefer the built-in one which accepts and returns integer. Manually force type conversion seems to be unavoidable.
