Very quiet here.. The readme states "Patches are also accepted as GitHub pull requests", is that no longer true? |

This is a suggested improvement to the documentation of
snd_pcm_state(). There is some confusion, probably caused by old bugs that could made it return a negative error code. This stuff is still floating around the internet and sometimes shows up in searches. This PR adds a comment intended to make it absolutely clear that there is never supposed to be a negative error code.
