+Description: Stop using alsa/iatomic.h
+             Technically this is an API breakage in libasound 1.1.2,
+             but it makes sense to me that this header was removed
+             by ALSA upstream.
+             .
+             bristol was the only user in Debian, and even here the
+             code that once used it was already commented out.
