Subject: [PATCH 73/87] ethernet: freescale: Remove memset after dma_alloc_coherent
Date:   Fri, 28 Jun 2019 01:46:41 +0800
Message-Id: <20190627174641.6474-1-huangfq.daxian@gmail.com>
To:     unlisted-recipients:; (no To-header on input)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In commit af7ddd8a627c
("Merge tag 'dma-mapping-4.21' of git://git.infradead.org/users/hch/dma-mapping"),
dma_alloc_coherent has already zeroed the memory.
So memset is not needed.
