Some suggestions to kernel newbies:

        avoid fixing compiler warnings  because the goal is to fix the
        CAUSE of the warnings (which is usually not obvious), not just
        to make the warnings go away 

Does that suggest the commit author be the best people to fix
warnings? The typical situation may be, the author is not aware of the
warnings at all: they are buried in the tedious output of make...

Thanks,
