From c3d9f24a392979cbd6a40d102c71eab018117f3e Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Tue, 17 Sep 2013 13:07:30 +0200 Subject: [PATCH] s390/eventfacility: allow childs to handle more than 1 event type Currently all handlers (quiesce, console) only handle one event type. Some drivers will handle multiple (compatible) event types. Rework the code accordingly.
