Yeah, that's true, the problem can be solved with this pattern too, and
this sounds a lot more stable than the current solution for this problem
on the IOMMU side. Currently this is 'solved' by making sure the iommu
driver is linked in before the KFD driver is, which affects the order of
the initcalls.
Anyway, it would be good to have a solution which removes the
differences between whether something is compiled-in or as a module,
because this reduces the testing matrix and makes everyones life easier.
For me it would be nice to know that if something works as a module, it
will still work when compiled in.
