[PATCH v2 0/1] arm64/dma-mapping: reduce an unnecessary conversion for coherent DMA

From: Zhen Lei
Date: Thu Mar 17 2016 - 22:30:42 EST


Changelog:
v1 -> v2:
1. Give up removing the conversion, because of thoughtless, instead moved it
into branch if (!is_device_dma_coherent(dev)). Thanks for Catalin's detailed
explanation, I directly take some relies as comment in the code.
