From 1ab50a99f8cc6f4d761421d55a4044ad7f185cb5 Mon Sep 17 00:00:00 2001 From: Sebastian Ott Date: Fri, 29 Jul 2016 10:43:53 +0200 Subject: [PATCH] s390/cio: remove subchannel_id from ccw_device_private A copy of struct subchannel_id is maintained in ccw_device_private. The subchannel id is a property of the subchannel. The additional copy is not needed. Internal users can obtain it from subchannel.schid - device drivers can use ccw_device_get_schid().
