[PATCH] pmac IDE: don't release empty interfaces
From: Thibaut VARENE <T-Bone@parisc-linux.org> 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. Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
