The patch titled
ALSA: cs5535audio: correctly set dma->substream
has been removed from the -mm tree. Its filename was
alsa-cs5535audio-correctly-set-dma-substream.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: ALSA: cs5535audio: correctly set dma->substream
From: Andres Salomon <dilinger@xxxxxxxxxx>
We're never actually setting dma->substream to the current substream; that
means the dma->substream checks that we do in the suspend/resume path are
never satisfied, and the PRD registers are never correctly managed. This
changes it so that we set the substream when constructing the specific bus
master DMA, and unsetting it when we tear down the BM's DMA.
