Note the duplicate test 'SCpnt->sc_data_direction == DMA_FROM_DEVICE'

from Documentation/DMA-API.txt:

                                              memory to the device
DMA_FROM_DEVICE       = PCI_DMA_FROMDEVICE    data is coming from
                                              the device to the
