I don't think that this is a good idea - what happens if two people call omap_iommu_add() for the same IOMMU device independently? The real problem here seems to be the TI DSP bridge code, and if that's the case why can't we just avoid registering IVA2 if the TI DSP bridge code is enabled. That solves your stated problem without creating additional management issues. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
