[PATCH -next 11/26] hisilicon: Use dma_zalloc_coherent

From: Joe Perches <joe@perches.com>
Date: 2014-06-15 20:38:47
Also in: lkml
Subsystem: hisilicon network subsystem driver, networking drivers, the rest · Maintainers: Jian Shen, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

Use the zeroing function instead of dma_alloc_coherent & memset(,0,)
