PS1, Line 482: 		goto init_err_cleanup_exit;
Just one comment to make this review not too boring: This actually changes
behavior. The original version failed to call pickit2_shutdown() if its
registration failed. It's a minor thing in this case (why would registration
fail?). Generally it's prefered though to focus on the functional changes
in the commit message (or just have them in a separate change).
