[PATCH v3 04/24] dmaengine: qcom_hidma: Remove call to memset after dmam_alloc_coherent
From: Fuqian Huang <hidden>
Date: 2019-07-15 03:17:32
Also in:
dmaengine, linux-arm-msm, lkml
Subsystem:
arm/qualcomm mailing list, dma generic offload engine subsystem, qualcomm hidma driver, the rest · Maintainers:
Vinod Koul, Sinan Kaya, 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.
