Subject: [ 014/120] drivers/dma/dmaengine.c: lower the priority of failed to get dma channel message

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Fabio Estevam <fabio.estevam@...escale.com>

commit 0eb5a35801df3c438ce3fc91310a415ea4452c00 upstream.

Do the same as commit a03a202e95fd ("dmaengine: failure to get a
specific DMA channel is not critical") to get rid of the following
messages during kernel boot:

  dmaengine_get: failed to get dma1chan0: (-22)
  dmaengine_get: failed to get dma1chan1: (-22)
  dmaengine_get: failed to get dma1chan2: (-22)
  dmaengine_get: failed to get dma1chan3: (-22)
  ..
