Subject: [PATCH] ASoC: omap-pcm: Initialize DMA configuration
Date: Mon, 25 Apr 2016 11:10:07 -0500 [thread overview]
Message-ID: <1461600607-19582-1-git-send-email-Linux.HWI@garmin.com> (raw)
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.
