Merge branch 'fixes' of git://git.infradead.org/users/vkoul/slave-dma
Pull slave-dmaengine fixes from Vinod Koul:
"Back from long weekend here in India and now the time to send fixes
for slave dmaengine.
- Dan's fix of sirf xlate code
- Jean's fix for timberland
- edma fixes by Sekhar for SG handling and Yuan for changing init
call"
* 'fixes' of git://git.infradead.org/users/vkoul/slave-dma:
dma: fix eDMA driver as a subsys_initcall
dmaengine: sirf: off by one in of_dma_sirfsoc_xlate()
platform: Fix timberdale dependencies
dma: edma: fix incorrect SG list handling
