From a894bd7fb539d671149fea9420c94c0fbe6baf7a Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Wed, 6 Nov 2013 10:16:20 +0000 Subject: ASoC: generic-dmaengine-pcm: Clear slave_config memory We currently assume that the DMA Slave Config will be fully populated by the platform, however some DMA Engines make decisions based on zero (default) flags such as DMA_SLAVE_BUSWIDTH_UNDEFINED and as this is a static declaration we need to memset it to clear the data area.
