From 719e25dba4430a7f2b1e77fa962f0527ebc9371d Mon Sep 17 00:00:00 2001 From: Fuqian Huang Date: Mon, 15 Jul 2019 11:17:23 +0800 Subject: dmaengine: qcom_hidma: Remove call to memset after dmam_alloc_coherent In commit 518a2f1925c3 ("dma-mapping: zero memory returned from dma_alloc_*"), dma_alloc_coherent has already zeroed the memory. So memset is not needed.
