It's incorrect.

The init section will be free'd, and as a result can be re-allocated to
other uses. Thus testing that data is not in the init-section makes no
sense.

Testing for _code_ not being in the init section can be sensible, since
code never gets re-allocated (modulo module code, but that's never in the
init section). So checking the "notifier_call" part may be sensible, but
checking the notifier block data pointer definitely is not.

Patches 1-2 applied.
