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

Pull slave-dmaengine updates from Vinod Koul:
 "Once you have some time from extended weekend celebrations please
  consider pulling the following to get:
   - Various fixes and PCI driver for dw_dmac by Andy
   - DT binding for imx-dma by Markus & imx-sdma by Shawn
   - DT fixes for dmaengine by Lars
   - jz4740 dmac driver by Lars
   - and various fixes across the drivers"

What "extended weekend celebrations"?  I'm in the merge window, who has
time for extended celebrations..
