From 85acc407bf1c49fb40b8f461c2c7526af736d87e Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Fri, 14 Nov 2008 18:18:06 +0100 Subject: [PATCH] [S390] cio: Fix refcount after moving devices. In ccw_device_move_to_orphanage(), a replacing ccw_device is searched via get_{disc,orphaned}_ccwdev_by_dev_id() which obtain a reference on the returned ccw_device. This reference must be given up again after the device has been moved to its new parent.
