A bit out of date, but not to the point of being useless. I still give them to juniors and interns that want to learn more about kernel work. There's also a much more recent (2022) book called Linux Device Driver Development published by packt. In general, these sorts of books are mainly useful for "what not to do", as general architecture stuff is usually well documented by source code examples and in-kernel docs.
