Instead of many individual conversion patches,
perhaps a script to do all the conversions at once.

Maybe:

pattern='(?:\/\*\s*fall(?:\s*|\s*\-\s*)thr(?:u|ough)\s*\*\/|\/\/\s*fall\s*thr(?:u|ough)\s*$)'
git grep -P -i --name-only "$pattern" -- '*.[ch]' |
    xargs perl -p -i -e "s/$pattern/__fallthrough;/gi"
