From a18f8e97fe69195823d7fb5c68a8d6565f39db4b Mon Sep 17 00:00:00 2001 From: Pawel Moll Date: Thu, 2 Apr 2015 18:50:32 +0100 Subject: bus: arm-ccn: Fix node->XP config conversion Events defined as watchpoints on nodes must have their config values converted so that they apply to the respective node's XP. The function setting new values was using wrong mask for the "port" field, resulting in corrupted value. Fixed now.
