From 134d12fae0bb8f3d60dc7440a9e1950bb5427167 Mon Sep 17 00:00:00 2001 From: Ohad Ben-Cohen Date: Sun, 4 Mar 2012 12:01:11 +0200 Subject: [PATCH 1/2] ARM: OMAP: fix iommu, not mailbox For some weird (freudian?) reason, commit 435792d "ARM: OMAP: make iommu subsys_initcall to fix builtin omap3isp" unintentionally changed the mailbox's initcall instead of the iommu's. Fix that.
