th it after we call riocm_put_channel(). That way we can check if it's NULL and avoid calling riocm_put_channel() on it twice. I renamed err_nodev to err_put_new_ch so that it better reflects what the goto does. Then because we had flipping things around, it means we don't neeed to initialize the pointers to NULL and we can remove an if statement and pull things in an indent level.
