The member 'private' of 'struct dma_chan' is meant for passing data between client and the controller driver. The DMA client driver may point it to platform specific stuff after acquiring the channel. So, it is the responsiblity of the same code to reset it, if it must. The DMA engine doesn't set it and hence, shouldn't reset it either. This reseting of private by DMA Engine comes in the way of implementing default channel settings during DMAC probe. That capability is useful for not having the clients to always provide platform specific data, like Rx/Tx FIFO addresses, which usually doesn't change across channel requests.
