hsr: off by one sanity check in hsr_register_frame_in()
This is a sanity check and we never pass invalid values so this patch doesn't change anything. However the node->time_in[] array has HSR_MAX_SLAVE (2) elements and not HSR_MAX_DEV (3). Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
