From 7a715f46012f3552294154978aed59cba9804928 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 27 Aug 2008 18:37:58 -0700 Subject: sparc: Make SBUS DMA interfaces take struct device. This is the first step in converting all the SBUS drivers over to generic dma_*(). Signed-off-by: David S.
