From ede23fa8161c1a04aa1b3bf5447812ca14b3fef1 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 26 Aug 2013 22:45:23 -0700 Subject: 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. Signed-off-by: Joe Perches Acked-by: Neil Horman Acked-by: Jesse Brandeburg Acked-by: Jeff Kirsher Signed-off-by: David S.
