So please read https://www.kernel.org/doc/Documentation/dynamic-debug-howto.txt as well. The ability to dynamically switch on and off debug messages per callsite is extremely useful. And it also enables you to switch on some extra info you often want, like function names, without having to explictly put them into every format string. I recommend setting CONFIG_DYNAMIC_DEBUG and taking a look at /sys/kernel/debug/dynamic_debug/control if you ever do any kernel development.
