From 96ae0f08ac574f3dac17cff9afdeee5562f61cbb Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 6 Jan 2014 17:19:22 +0100 Subject: ASoC: mxs: Remove SND_DMAENGINE_PCM_FLAG_NO_RESIDUE flag Since commit 7b11304 ("dma: mxs-dma: Report correct residue for cyclic DMA") the mxs dmaengine driver has support for residue reporting. So there is no need to specify the SND_DMAENGINE_PCM_FLAG_NO_RESIDUE flag anymore. This allows a finer grained resolution for the PCM pointer as well as avoids the race condition that can occur with the period counting that is used when the dmaengine driver does not support residue reporting.
