Message-ID: <1377582323.2658.10.camel@joe-AO722>
Date: Mon, 26 Aug 2013 22:45:23 -0700
From: Joe Perches <joe@...ches.com>
To: netdev@...r.kernel.org

Subject: [PATCH net-next] drivers:net: Convert
dma_alloc_coherent(...__GFP_ZERO) to dma_zalloc_coherent
__GFP_ZERO is an uncommon flag and perhaps is better
not used. static inline dma_zalloc_coherent exists
so convert the uses of dma_alloc_coherent with __GFP_ZERO
to the more common kernel style with zalloc.
Remove memset from the static inline dma_zalloc_coherent
and add just one use of __GFP_ZERO instead.
Trivially reduces the size of the existing uses of
dma_zalloc_coherent.
Realign arguments as appropriate.
