Subject: [PATCH] ASoC: atmel-pcm-dma: won't check direction when configure dma
Date: Mon, 2 Feb 2015 14:44:46 +0800	[thread overview]
Message-ID: <1422859486-11051-1-git-send-email-voice.shen@atmel.com> (raw)

As DMA framework request DMA using direction only in prep_slave
function, (The At91 xdma driver has adapted to this request).
So won't check direction when do DMA configuration.
