+Subject: [FYI PATCH] ASOC:TWL4030 Audio capture fix
+
+A couple of folks have noticed an issue with audio capture -- the
+capture result is always silence.
+
+The patch below is a quick fix for those with this issue.  There are
+substantial changes to the codec driver that will be trickling down
+from ASoC, and they deal with this issue differently.
+
+So consider this as a bandaid for those who don't want to wait for the
+trickle down :-)
+
+Steve
