From fba51bae8c3797034f497ed68f4ed120a903f941 Mon Sep 17 00:00:00 2001 From: Thibaut VARENE Date: Fri, 18 Nov 2005 22:37:37 +0100 Subject: [PATCH] [PATCH] pmac IDE: don't release empty interfaces From: Thibaut VARENE Cleaning up the hwif without knowing its previous state in pmac.c is a big and potentially dangerous job, and there seems to be no generic code interface that would provide either a way to properly release an hwif or to clean it up. Fixes OOPS for empty PMAC interface and add-on PCI controller.
