Subject: [PATCH 24/87] infiniband: hns: Remove memset after dma_alloc_coherent in hns_roce_hw_v2.c
Date: Fri, 28 Jun 2019 01:37:32 +0800 [thread overview]
Message-ID: <20190627173732.3095-1-huangfq.daxian@gmail.com> (raw)
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.
