    iommu: Finish making iommu_group support mandatory · 05f80300
    Robin Murphy authored
    Now that all the drivers properly implementing the IOMMU API support
    groups (I'm ignoring the etnaviv GPU MMUs which seemingly only do just
    enough to convince the ARM DMA mapping ops), we can remove the FIXME
    workarounds from the core code. In the process, it also seems logical to
    make the .device_group callback non-optional for drivers calling
    iommu_group_get_for_dev() - the current callers all implement it anyway,
    and it doesn't make sense for any future callers not to either.
