Subject: [PATCH v2 0/1] arm64/dma-mapping: reduce an unnecessary conversion for coherent DMA
Date: Fri, 18 Mar 2016 10:26:06 +0800 [thread overview]
Message-ID: <1458267967-6332-1-git-send-email-thunder.leizhen@huawei.com> (raw)
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.
