Subject: [PATCH] powerpc: pseries: Avoid spurious error during hotplug CPU add

From: Anton Blanchard <[email-masked]>
Date: Mon, 15 Aug 2011 10:30:30 +1000

During hotplug CPU add we get the following error:

Unexpected Error (0) returned from configure-connector

ibm,configure-connector returns 0 for configuration complete, so
catch this and avoid the error.
