Subject: [PATCH v2 03/27] atm: idt77252: remove memset after dma_alloc_coherent
Date: Fri, 28 Jun 2019 10:46:13 +0800 [thread overview]
Message-ID: <20190628024613.14929-1-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.
