This function is nice for debugging. I'd prefer to keep it with the fix. Jaroslav

I'd prefer to keep it with the fix. I'm find in either way; just submit a fix patch, then. thanks, Takashi

It's generally considered a best practice to delete unused code. If there is something you especially like for upcoming code, you still have git history, and even a lore.kernel.org link, to bookmark it. So I'd recommend going with v2, but of course it's your call! :) thanks,

dump_config_tree() is declared to return an int, but the compiler cannot prove that it always returns any value at all. This leads to a clang warning, when building via: make LLVM=1 -C tools/testing/selftests Furthermore, Mark Brown noticed that dump_config_tree() isn't even used anymore, so just delete the entire function.
