We are (and technically we've had this since May 2014) a community project. The ELC-E talk about using coverity reminded me to go give things a spin and see what comes out. Right now I'm trying to figure out the best way to get coverage for all of our different build targets or if we may have to just go with building sandbox only for maximal coverage (and make use of something like CONFIG_COMPILE_TEST_ONLY from the kernel). There is a way to make all defects publically viewable but I don't know if that's a great idea or not (I don't see anything super duper worrying but I also haven't really triaged everything) but anyone from the community can sign up and join the project.

We have the protocol and subclass variables which are used only in disabled debug code. This code dates back to the initial git import and seemingly dead code so remove it.
