Florian Meier	7f5ae35536	dmaengine: Add DMA_PRIVATE to BCM2835 driver ... Without DMA_PRIVATE the driver is not able to allocate more than one channel. Since it uses dma_get_any_slave_channel that calls private_candidate, the second allocation fails at /* some channels are already publicly allocated */ Maybe it should be fixed in the core, but at least this fixes the bug.
