From d4ba7854c9ea388e83731ee4b3c6546076f70f9d Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Thu, 25 Aug 2011 15:54:55 +0200 Subject: [PATCH] ASoC: imx-ssi: use dma_writecombine consistently If the channel is allocated as writecombine, then mmaping it should also use writecombine. Also, add a proper device for the call. Ported from a similar fix for mach-mxs.
