From 340601043df518d6f4f82da285c60c785ac8a716 Mon Sep 17 00:00:00 2001 From: Stephen Rothwell Date: Mon, 24 Oct 2005 17:40:23 +1000 Subject: powerpc: Add a shutdown member to vio_driver Add a shutdown member to struct vio_driver. We also need vio_bus_shutdown() which converts from struct device to struct vio_dev and knows how to extract the struct vio_driver. Original patch adjusted for different location of vio.c.
