[PATCH v3 03/24] dmaengine: imx-sdma: Remove call to memset after dma_alloc_coherent
From: Fuqian Huang <hidden>
Date: 2019-07-15 03:17:25
Also in:
dmaengine, lkml
Subsystem:
dma generic offload engine subsystem, the rest · Maintainers:
Vinod Koul, Linus Torvalds
In commit 518a2f1925c3
("dma-mapping: zero memory returned from dma_alloc_*"),
dma_alloc_coherent has already zeroed the memory.
So memset is not needed.
