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()
