From f2962dae0efd81fed06d0687f300725ab063587a Mon Sep 17 00:00:00 2001 From: Sebastian Ott Date: Tue, 15 May 2012 17:49:12 +0200 Subject: s390/ccwgroup: introduce ccwgroup_create_dev Add a new interface for drivers to create a group device. Via the old interface ccwgroup_create_from_string we would create a virtual device in a way that only the caller of this function would match and bind to. Via the new ccwgroup_create_dev we stop playing games with the driver core and directly set the driver of the new group device. For drivers which have todo additional setup steps (like setting driver_data) provide a new setup driver callback.
