From 3e70e67b390b1159b1d3243aec1194e37c4db33b Mon Sep 17 00:00:00 2001 From: Alexander Shiyan Date: Fri, 2 Apr 2021 11:14:05 +0300 Subject: ASoC: fsl_esai: Fix TDM slot setup for I2S mode [ Upstream commit e7a48c710defa0e0fef54d42b7d9e4ab596e2761 ] When using the driver in I2S TDM mode, the fsl_esai_startup() function rewrites the number of slots previously set by the fsl_esai_set_dai_tdm_slot() function to 2. To fix this, let's use the saved slot count value or, if TDM is not used and the number of slots is not set, the driver will use the default value (2), which is set by fsl_esai_probe().
