starting to patch kernel

Hi I am experienced embedded Linux driver developer. I have some spare time which I want to contribute to mainstream Linux kernel. Unfortunately http://kernelnewbies.org/KernelJanitors/Todo is very old. Can you please suggest small tasks good for start? It can be code clean up, API updates.
