[PATCH] style: Add parentheses to function names in comments

[Laurent Vivier <lvivier@redhat.com>]

The commit updates the style of function comments by adding parentheses
to function names in the descriptions where they are missing.

Done with:

---------8<------ fix_function_name.awk ---------8<------
/^\/\*\*/ {
    check_next = 1;
    print $0
    next
}
check_next == 1 && / \* struct/ {
    check_next = 0
    print $0
    next
}
check_next == 1 && / \* enum/ {
    check_next = 0
    print $0
    next
}
check_next == 1 && /^ \* [^ (]* -/ {
   modified_line = gensub(/^ \* ([^ ]*) -(.*)$/, " * \\1() -\\2", "g", $0)
   print modified_line
   check_next = 0;
   next
}
{
    print $0
    check_next = 0
}
---------8<------ fix_function_name.awk ---------8<------

Then

for file in *.[ch]; do
    cp ${file} ${file}.tmp && \
    awk -f fix_function_name.awk ${file}.tmp > ${file}
done
