Just fyi:
the treewide converted sysfs_emit uses
end up with these integer outputs:
$ git grep -P -oh 'sysfs_emit\(buf, "%\d*[luixd]*\\n"' | \
sort | uniq -c | sort -rn
1482 sysfs_emit(buf, "%d\n"
549 sysfs_emit(buf, "%u\n"
118 sysfs_emit(buf, "%ld\n"
100 sysfs_emit(buf, "%lu\n"
78 sysfs_emit(buf, "%llu\n"
62 sysfs_emit(buf, "%i\n"
47 sysfs_emit(buf, "%x\n"
24 sysfs_emit(buf, "%lld\n"
12 sysfs_emit(buf, "%llx\n"
12 sysfs_emit(buf, "%08x\n"
12 sysfs_emit(buf, "%02x\n"
10 sysfs_emit(buf, "%016llx\n"
8 sysfs_emit(buf, "%04x\n"
6 sysfs_emit(buf, "%lx\n"
5 sysfs_emit(buf, "%02d\n"
4 sysfs_emit(buf, "%04d\n"
2 sysfs_emit(buf, "%08lx\n"
