+Subject: [PATCH] MLK-14935: ASoC: fsl_sai: Fix mixing initialization data with
+ actual audio samples
+
+When starting a playback the initialization data used to reduce underruns
+was send to the transmit data register after the DMA requests were enabled.
+This patch moves the initialization phase before enabling the DMA so the
+data is transmitted in correct order.
