From 958974fb596ad037fb571cf2899f783764a83e1a Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Fri, 12 Oct 2007 16:11:21 +0200 Subject: [PATCH] [S390] cio: Introduce ccw_bus_type.shutdown. Introduce a shutdown method for the ccw bus that calls the driver specific shutdown method in struct ccw_driver. Switch zfcp to the new ccw_driver shutdown method.
