+Subject: [PATCH 63/73] ASoC: dapm: Fix _PRE and _POST events for DAPM
+ performance improvements
+
+commit 0ff97ebf0804d2e519d578fcb4db03f104d2ca8c upstream.
+
+Ever since the DAPM performance improvements we've been marking all widgets
+as not dirty after each DAPM run. Since _PRE and _POST events aren't part
+of the DAPM graph this has rendered them non-functional, they will never be
+marked dirty again and thus will never be run again.
+
+Fix this by skipping them when marking widgets as not dirty.
