Pull slave-dmaengine update from Vinod Koul:
 "This time we have a new dmaengine driver from the tegra folks.  Also
  we have Guennadi's cleanup of sh drivers which incudes a library for
  sh drivers.  And the usual odd fixes in bunch of drivers and some nice
  cleanup of dw_dmac from Andy."

Fix up conflicts in drivers/mmc/host/sh_mmcif.c
