The DMA_PREP_FENCE is to be used when preparing Tx descriptor if output of Tx descriptor is to be used by next/dependent Tx descriptor. The DMA_PREP_FENSE will not be set correctly in do_async_gen_syndrome() when calling dma->device_prep_dma_pq() under following conditions: 1. ASYNC_TX_FENCE not set in submit->flags 2. DMA_PREP_FENCE not set in dma_flags 3. src_cnt (= (disks - 2)) is greater than dma_maxpq(dma, dma_flags) This patch fixes DMA_PREP_FENCE usage in do_async_gen_syndrome() taking inspiration from do_async_xor() implementation.
