From b8ab0ccc0b6e517ff595f1b06fb9f578c8b4001f Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Tue, 17 Jan 2017 14:16:42 +0100 Subject: [PATCH] ASoC: Revert "samsung: Remove unneeded initialization of chan_name" This reverts commit cdaf9af1eaeb539e32bfd6da6310b41ad6c3ba23 which breaks I2S support on the non-DT Samsung SoC platforms, since the default "tx", "rx" DMA channel names for playback and capture streams or custom channel names in struct snd_dmaengine_pcm_config are supported in the ASoC dmaengine module only for devicetree booting case.
