Merge branch 'next' of git://git.infradead.org/users/vkoul/slave-dma
* 'next' of git://git.infradead.org/users/vkoul/slave-dma: (63 commits) dmaengine: mid_dma: mask_peripheral_interrupt only when dmac is idle dmaengine/ep93xx_dma: add module.h include pch_dma: Reduce wasting memory pch_dma: Fix suspend issue dma/timberdale: free_irq() on an error path dma: shdma: transfer based runtime PM dmaengine: shdma: protect against the IRQ handler dmaengine i.MX DMA/SDMA: add missing include of linux/module.h dmaengine: delete redundant chan_id and chancnt initialization in dma drivers dmaengine/amba-pl08x: Check txd->llis_va before freeing dma_pool dmaengine/amba-pl08x: Add support for sg len greater than one for slave transfers serial: sh-sci: don't filter on DMA device, use only channel ID ARM: SAMSUNG: Remove Samsung specific enum type for dma direction ASoC: Samsung: Update DMA interface spi/s3c64xx: Merge dma control code spi/s3c64xx: Add support DMA engine API ARM: SAMSUNG: Remove S3C-PL330-DMA driver ARM: S5P64X0: Use generic DMA PL330 driver ARM: S5PC100: Use generic DMA PL330 driver ARM: S5PV210: Use generic DMA PL330 driver ...
