Merge branch 'fixes' of git://git.infradead.org/users/vkoul/slave-dma

Pull slave-dmaengine fixes from Vinod Koul:
 "Two fixes for slave-dmaengine.

  The first one is for making slave_id value correct for dw_dmac and
  the other one fixes the endieness in DT parsing"

* 'fixes' of git://git.infradead.org/users/vkoul/slave-dma:
  dw_dmac: adjust slave_id accordingly to request line base
  dmaengine: dw_dma: fix endianess for DT xlate function
