Mainline kernel documentation has already warned this in advance:
Note that it makes no sense for a function marked with __init to be exported
to modules with EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL()- this will break.
Commit 1b9980fb24 introduced with Linux 4.9.321 fixes modpost behavior so the
previously uncaught poor use of EXPORT_SYMBOL() on __init functions were caught
by the script for good.
While this commit is intended to resolve such bad behavior, this also acts as a
cleanup commit for such functions as there are no other drivers that need to
call affected __init functions (at least within kernel itself, and we shouldn't
unless you're techpack/audio). We make them static instead in this case.
