Odd use of %14pM in net/batman-adv/distributed-arp-table.c

An output mac address is 17 bytes
1
12345678901234567
00:11:22:33:44:55
but in net/batman-adv/distributed-arp-table.c
int batadv_dat_cache_seq_print_text(struct seq_file *seq, void *offset)
{
[...]
seq_printf(seq, " * %15pI4 %14pM %4i %6i:%02i\n",
&dat_entry->ip, dat_entry->mac_addr,
batadv_print_vid(dat_entry->vid),
last_seen_mins, last_seen_secs);
%14pM is odd as this should not emit the last byte of the
mac address. So given the example above, it would output
00:11:22:33:44
Is that what's really desired?
If so, I'd suggest using something more obvious like %5phC
