Missing period at the end.

This default seems a bad cargo cult. Why ARM64 kernel should have all them be
opt-out, instead of opt-in? Shouldn't this be a distro problem?

Is it real one?

Leave trailing comma here as it's not a terminator.

Ditto.

Ditto.

Drop this ugly ifdeffery.

No comma for the terminator.

Drop the rather problematic of_match_ptr().
