From fd23b7dee5e4d369f620979cb120f53629389355 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Fri, 19 Mar 2010 14:52:55 +0000 Subject: ASoC: move dma_data from snd_soc_dai to snd_soc_pcm_stream This fixes a memory corruption when ASoC devices are used in full-duplex mode. Specifically for pxa-ssp code, where this pointer is dynamically allocated for each direction and destroyed upon each stream start. All other platforms are fixed blindly, I couldn't even compile-test them. Sorry for any breakage I may have caused.
