From 533b40cccd2fbe8cf6ba361cab7e99f626be45bf Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Wed, 22 Oct 2014 17:22:22 -0500 Subject: [PATCH] iommu/omap: Remove conditional definition of dev_to_omap_iommu() The dev_to_omap_iommu() is local to the OMAP IOMMU modules, and need not be defined conditionally. The CONFIG_IOMMU_API dependency check was added in the past to fix a compilation issue back when the header resided in the arch/arm layers, and is no longer needed. While at this, fix the header against double inclusion as well.
