Subject: [PATCH 38/87] ethernet: atlx: remove memset after pci_alloc_consistent in atl2.c
Date: Fri, 28 Jun 2019 01:40:39 +0800	[thread overview]
Message-ID: <20190627174040.4180-1-huangfq.daxian@gmail.com> (raw)

pci_alloc_consitent 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.
