Subject[PATCH] ASoC: omap-pcm: Initialize DMA configuration
Date
From: Jim Lodes <jim.lodes@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.
