From a8983d4b0a8c439bddae0c9fd1e8a4cf7c402262 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 10 Dec 2013 12:34:46 -0700 Subject: ASoC: ep93xx: remove custom DMA alloc compat function ep93xx_compat_request_channel() is almost identical to dmaengine_pcm_compat_request_channel(), with the exception that the latter: a) Assumes that the DAI DMA data is a struct snd_dmaengine_dai_dma_data pointer rather than some custom type. b) dma_data->filter_data rather than dma_data should be passed to snd_dmaengine_pcm_request_channel() as the filter data. Make minor changes to the ep93xx DAI drivers so that those two conditions are met. This allows removal of the custom .compat_request_channel().
