For the record, I don't really like boilerplate, but fixing the boilerplates
all at once is at least better than fixing them one at a time.

Would you want to prepare a patch handling all of these ?

$ find src/ -name '*.c' -type f -print0 |xargs -r0 awk '{fn=gensub(".*/", "", "1", FILENAME)}
FILENAME~/scripts/{fn=gensub("\\.c","", 1, fn)} FNR==1 && /---/{top=1} /\*\//{top=0} !top{next} FNR==3 && NF==2 &&
$2!=fn{printFILENAME,"head",fn,$2} /IDENTIFICATION/{getline; if ($0!~FILENAME){print FILENAME,"foot",$2}}'

There's some function comments wrong too.
In case someone want to fix them together.

    Wrong function name in header comment
    
    Found like this
    
    for f in `find src -type f -name '*.c'`; do awk -v p=0 '/^\/\* *-*$/{h=$0; getline; h=h"\n"$0; g=gensub(
"[^_[:alnum:]].*","", 1, $2); p=1} 0&&/^{/{p=0; print h}; /^ \*\/$/{h=h"\n"$0; getline a; h=h"\n"a; getline f;
h=h"\n"f;l=length(g); if (substr(f,1,7) == substr(g,1,7) && substr(f,1,l) != substr(g,1,l)) print FILENAME,g,f,"\n"h;
next}0&&/^[^s/ {]/{p=0; h=""; next} 0&&p{h=h"\n"$0}' "$f"; done |less
