Good question, if this was part of a series. If it was and can not be removed
in isolation, it nevertheless introduces a regression. Obviously there was
a reason for using postcore_initcall (which is quite evident in the crash),
and I don't think it is a good idea to just change it without addressing
the reason(s) first. Who knows what other platforms crash because of this
change.
