thunderbolt: Fix off by one in tb_port_find_retimer()
This array uses 1-based indexing so it corrupts memory one element beyond of the array. Fix it by making the array one element larger. Fixes: dacb12877d92 ("thunderbolt: Add support for on-board retimers") Cc: stable@vger.kernel.org Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
