Ludovic Desroches 6b373d53e8 dmaengine: at_xdmac: double FIFO flush needed to compute residue ... commit 9295c41d77 upstream. Due to the way CUBC register is updated, a double flush is needed to compute an accurate residue. First flush aim is to get data from the DMA FIFO and second one ensures that we won't report data which are not in memory.
