From 5fa70f71dbf33603b0d29b33d8da128b266eb733 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Wed, 3 Apr 2013 11:02:56 +0200 Subject: [PATCH] ASoC: dmaengine_pcm: Setup device_fc in snd_hwparams_to_dma_slave_config Usually device_fc should be set to false for audio DMAs. Initialize it in a common place so drivers don't have to do this manually.
