Function declaration 'iopgtable_lookup_entry' is missing from header
file.

Is this done because of any error?
You may add a comment on why this is required.

The function is exported by iommu module, but no other driver is using
it so far. So, it's wrong but currently we have only a sparse warning.
I can add this information to the patch description.
