From 110743189c863e96dc08a581d56c50b965870a3f Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Wed, 4 Jul 2018 10:49:43 +0100 Subject: [PATCH] ASoC: qdsp6: q6afe-dai: do not close port if its not opened afe ports are open as part of prepare, so for use cases like "aplay sample.wav" were sample.wav is not present. This would call port close eventhough port was never opened. DSP would return errors for such use cases. Avoid doing this by checking the port state.
