Merge tag 'dmaengine-4.10-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul: "Fairly routine update this time around with all changes specific to drivers: - New driver for STMicroelectronics FDMA - Memory-to-memory transfers on dw dmac - Support for slave maps on pl08x devices - Bunch of driver fixes to use dma_pool_zalloc - Bunch of compile and warning fixes spread across drivers" [ The ST FDMA driver already came in earlier through the remoteproc tree ] * tag 'dmaengine-4.10-rc1' of git://git.infradead.org/users/vkoul/slave-dma: (68 commits) dmaengine: sirf-dma: remove unused ‘sdesc’ dmaengine: pl330: remove unused ‘regs’ dmaengine: s3c24xx: remove unused ‘cdata’ dmaengine: stm32-dma: remove unused ‘src_addr’ dmaengine: stm32-dma: remove unused ‘dst_addr’ dmaengine: stm32-dma: remove unused ‘sfcr’ dmaengine: pch_dma: remove unused ‘cookie’ dmaengine: mic_x100_dma: remove unused ‘data’ dmaengine: img-mdc: remove unused ‘prev_phys’ dmaengine: usb-dmac: remove unused ‘uchan’ dmaengine: ioat: remove unused ‘res’ dmaengine: ioat: remove unused ‘ioat_dma’ dmaengine: ioat: remove unused ‘is_raid_device’ dmaengine: pl330: do not generate unaligned access dmaengine: k3dma: move to dma_pool_zalloc dmaengine: at_hdmac: move to dma_pool_zalloc dmaengine: at_xdmac: don't restore unsaved status dmaengine: ioat: set error code on failures dmaengine: ioat: set error code on failures dmaengine: DW DMAC: add multi-block property to device tree ...
