When doing dma_alloc_coherent in the driver, we add a certain hard-coded offset to the DMA address before returning to the callee function. This offset is needed when our device use this DMA address to perform outbound transactions to the host. However, if we want to map the DMA'able memory to the user via dma_mmap_coherent(), we need to pass the original dma address, without this offset. Otherwise, we will get erronouos mapping.
