From d526e85f60fce9aa2a1432cbd06e3cf20c1644c8 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Fri, 14 Dec 2012 10:32:52 +1100 Subject: powerpc+of: Rename and fix OF reconfig notifier error inject module This module used to inject errors in the pSeries specific dynamic reconfiguration notifiers. Those are gone however, replaced by generic notifiers for changes to the device-tree. So let's update the module to deal with these instead and rename it along the way.
