[alsa-devel] [PATCH] ASoC: omap-pcm: Initialize DMA configuration

[J.D. Schroeder]

From: Jim Lodes <jim.lodes at garmin.com>

Initialize the dma_slave_config for PCM DMA transfers,
instead of leaving it uninitialized. Keeps previous data on
the stack from giving us invalid values in uninitialized
members of the config structure.
