Suman Anna c5cf5c5377 iommu/omap: Fix bus error on debugfs access of unattached IOMMU ... Any debugfs access on an OMAP IOMMU that is not enabled (done during attach) results in a bus error due to access of registers without the clock or the reset enabled for the respective IOMMU. So, add a check to make sure the IOMMU is enabled/attached by a client device. This gracefully prints a "Operation not permitted" trace when the corresponding IOMMU is not enabled.
