ASoC: dapm: Fix _PRE and _POST events for DAPM performance improvements
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. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com> Cc: stable@vger.kernel.org
