Since Linux 4.21 we merged the swiotlb ops into the DMA direct ops, so they would always have a the sync_single methods. But late in the cicle we also removed the direct ops entirely, so we'd see NULL DMA ops. Switch vmw_dma_select_mode to only detect swiotlb presence using swiotlb_nr_tbl() instead. Fixes: |
