From 738f2b7b813913e651f39387d007dd961755dee2 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 27 Aug 2008 18:09:11 -0700 Subject: sparc: Convert all SBUS drivers to dma_*() interfaces. And all the SBUS dma interfaces are deleted. A private implementation remains inside of the 32-bit sparc port which exists only for the sake of the implementation of dma_*(). Signed-off-by: David S.
