Subject: serial167: fix read buffer overflow
From: Roel Kluin <roel.kluin@xxxxxxxxx>
Check whether index is within bounds before grabbing the element.
Also, since NR_PORTS is defined ARRAY_SIZE(cy_port), cy_port[NR_PORTS] is
out of bounds as well.
[akpm@xxxxxxxxxxxxxxxxxxxx: cleanup, remove (long) casts]
