^^Nit: presumably you meant "Allow" in the subject.

Both of these patches look fine to me, but you probably need to check
the setting of MODULE_OWNER after:
https://lore.kernel.org/r/f4de29d8330981301c1935e667b507254a2691ae.1616157612.git.robin.mur...@arm.com
Right, furthermore I would rather expect these patches on their own to
hit the problem that my patch tries to avoid - where since mtk_iommu_ops
is const, the current version of iommu_device_set_ops() is liable to
blow up trying to write to rodata.
In fact I do wonder a little why that wasn't happening already - maybe
the compiler is clever enough to tell that the assignment is redundant
when THIS_MODULE == 0, and elides it :/
