Merge branch 'fixes' of git://git.infradead.org/users/vkoul/slave-dma
Pull slave-dmaengine fixes from Vinod Koul:
"The first one fixes issue in pl330 to check for DT compatible and
the second one fixes omap-dma to start without delay"
* 'fixes' of git://git.infradead.org/users/vkoul/slave-dma:
dmaengine: omap-dma: Start DMA without delay for cyclic channels
DMA: PL330: Add check if device tree compatible
