From a728b977429383b3fe92b6e3bff9e69365609e0f Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Tue, 8 Jul 2014 10:37:37 -0300 Subject: [PATCH] ARM: mvebu: Fix coherency bus notifiers by using separate notifiers Currently, the coherency fabric support registers two bus notifiers; one for platform, one for pci bus types, with the same notifier block. However, this is illegal and can cause serious issues: the notifier block is also a link in the notifier list and cannot be inserted twice. This commit fixes this by using different notifier blocks (with the same notifier callback) to set the platform and pci bus types notifiers.
