If you mean "am I sure the loop iterates at least once", then yes, as
we have an explicit check just before the concerned list_for_each_entry():
/*
* This should never happen; we return above if we fail to
* allocate and we should never be in this code if there are
* no registers at all.
*/
if (list_empty(&map->debugfs_off_cache)) {
WARN_ON(list_empty(&map->debugfs_off_cache));
return base;
}
Best regards,
