I see, interesting inconsistency, but that's what we have to live with. .. I just have noticed that you haven't used the updated base for your series, you need to take Greg's KH tty tree and use tty-next / tty-testing branch(es). Speaking of base, start using --base when preparing patches, it helps CIs to test against correct branches. -- With Best Regards, Andy Shevchenko
