Subject: [PATCH 75/87] ethernet: marvell: remove memset after pci_alloc_consistent
Date: Fri, 28 Jun 2019 01:46:45 +0800 [thread overview]
Message-ID: <20190627174645.6521-1-huangfq.daxian@gmail.com> (raw)
pci_alloc_consistent calls dma_alloc_coherent directly.
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.
