Subject: [PATCH v3 02/24] atm: idt77252: Remove call to memset after dma_alloc_coherent
Date:   Mon, 15 Jul 2019 11:17:09 +0800
Message-Id: <20190715031709.6281-1-huangfq.daxian@gmail.com>
To:     unlisted-recipients:; (no To-header on input)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In commit 518a2f1925c3
("dma-mapping: zero memory returned from dma_alloc_*"),
dma_alloc_coherent has already zeroed the memory.
So memset is not needed.
