[PATCH] ASoC: atmel-pcm-dma: won't check direction when configure dma

From: Bo Shen
Date: Mon Feb 02 2015 - 01:45:17 EST


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.
