Most likely due to a copy-paste mistake the dst_addr member of the dma_slave_config structure has been marked as ignored if the !source! address belong to the memory. That is relevant to the src_addr field of the structure while the dst_addr field as containing a destination device address is supposed to be ignored if the destination is the CPU memory. Let's fix the field description accordingly.
