This doesn't make much sense to me as a fix - it feels like we're doing
a fragile hack.  Surely it's better to do this as we register the
devices, that way we're also protected against any similar issues with
this that might occur after late probe if things are built modular?  Or
is there a strong reason for doing this only at late_initcall?
