While that __ref is actually missing since the blamed commit, modpost
only warns about .data -> .exit.text mismatches since
f177cd0c15fc ("modpost: Don't let "driver"s reference .exit.*")
(currently in next). So if your goal is to silence warnings in stable,
patches of this type don't need to be backported unless f177cd0c15fc is
backported, too. (But they don't hurt either.)
Best regards
