From: Hiroshi DOYU <[email protected]> The function prefix "omap2_iommu_" indicates that the prefixed function belongs to "omap2_iommu_ops" to provide iommu basic functionalities for the above layers. It's better to avoid the prefixed function called in the same prefixed ones internally, like nested here. Now "iommu_disable" is called just after fault_isr() in the above layer. This is a little bit more sensible to keep the consistency of module layers.
