Subject: [PATCH 10/87] block: skd_main.c: Remove call to memset after dma_alloc_coherent
Date: Fri, 28 Jun 2019 01:35:16 +0800 [thread overview]
Message-ID: <20190627173516.2351-1-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.
