If multiple people have asked this, perhaps it'd be a good idea to
include the answer in the commit description.

Being defined as a "bool" sounds like a reasonable reason that no
remove() is required.

Being loaded via postcore_initcall() (a) should have absolutely no
influence over whether a remove() is required (an actual module could
just as well include a postcore_initcall function, which would get
executed at module load time), and (b) is wrong; initcall ordering
shouldn't be used to influence driver probe ordering.
