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. Signed-off-by: Suman Anna <s-anna@ti.com> --- drivers/iommu/omap-iommu.h | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-)
