#     Merge tag 'dma-mapping-4.20-3' of git://git.infradead.org/users/hch/dma-mapping
#     
#     Pull dma-mapping fixes from Christoph Hellwig:
#      "Two dma-direct / swiotlb regressions fixes:
#     
#        - zero is a valid physical address on some arm boards, we can't use
#          it as the error value
#     
#        - don't try to cache flush the error return value (no matter what it
#          is)"
#     
#     * tag 'dma-mapping-4.20-3' of git://git.infradead.org/users/hch/dma-mapping:
#       swiotlb: Skip cache maintenance on map error
#       dma-direct: Make DIRECT_MAPPING_ERROR viable for SWIOTLB
