Merge tag 'ux500-dma40-for-arm-soc-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/drivers
From Linus Walleij: DMA40 fixes for earlier submitted driver patches: - Fix various error path and sparse bugs in the DMA40 driver - Fix various compile errors in the ux500 crypto driver (dependent on the DMA40 changes). * tag 'ux500-dma40-for-arm-soc-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson: crypto: ux500: use dmaengine_submit API crypto: ux500: use dmaengine_prep_slave_sg API crypto: ux500: use dmaengine_device_control API crypto: ux500/crypt: add missing __iomem qualifiers crypto: ux500/hash: add missing static qualifiers crypto: ux500/hash: use readl on iomem addresses dmaengine: ste_dma40: Declare memcpy config as static dmaengine: ste_dma40: fix error return code in d40_probe() Signed-off-by: Olof Johansson <olof@lixom.net>
