Subject: dm: simplify the loop in lists_driver_lookup_name()

dm: simplify the loop in lists_driver_lookup_name()

if (strncmp(name, entry->name, len))
                continue;

        /* Full match */
        if (len == strlen(entry->name))
                return entry;

is equivalent to:

        if (!strcmp(name, entry->name))
                return entry;

The latter is simpler.
