[alsa-devel] [PATCH 09/19] ASoC: rsnd: move rsnd_gen_dma_addr() from gen.c to dma.c
Kuninori Morimoto
kuninori.morimoto.gx at renesas.com
Thu Feb 19 04:52:09 CET 2015
From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>
Now, we have dma.c for Audio DMAC / Audio DMAC peri peri.
rsnd_gen_dma_addr() should go there.
