micro-optimizations are great, if you can actually measure them and they
matter :)

If you are looking for someplace to start, might I recommend the
drivers/staging/ directory?  I take all sorts of "basic" cleanup
patches, and there are loads of things to do in there.  Look at the
drivers/staging/*/TODO files for specific examples of what needs to be
done to get these files cleaned up and fixed properly.

Hope this helps,
