Subject: linux-next: manual merge of the sound tree with the sound-asoc-fixes
 tree

Hi all,

Today's linux-next merge of the sound tree got a conflict in:

  sound/core/pcm_dmaengine.c

between commit:

  e8343410ddf08 ("ALSA: dmaengine: Synchronize dma channel after drop()")

from the sound-asoc-fixes tree and commit:

  6a7db25aad8ce ("ALSA: dmaengine_pcm: terminate dmaengine before synchronize")

from the sound tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
