dmaengine: Add DMA_PRIVATE to BCM2835 driver 2014-01-20T07:01:50+00:00 Florian Meier florian.meier@koalo.de 2014-01-17T17:06:29+00:00 7f5ae3553685d54413dda4fc3c98f46056ea716b 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.
