swiotlb: Skip cache maintenance on map error (2018-11-21 18:47:58 +0100)
----------------------------------------------------------------
Two dma-direct / swiotlb regressions fixes
- 0 is a valid physical address on some arm boards, we can't use
0 as the error value
- don't try to cache flush the error return value (no matter what it is)
----------------------------------------------------------------
Robin Murphy (2):
dma-direct: Make DIRECT_MAPPING_ERROR viable for SWIOTLB
swiotlb: Skip cache maintenance on map error
