serial: arc_uart: Fix out-of-bounds access through DT alias

2018-05-30T05:49:15+00:00

[ Upstream commit f9f5786987e81d166c60833edcb7d1836aa16944 ] The arc_uart_ports[] array is indexed using a value derived from the "serialN" alias in DT, which may lead to an out-of-bounds access. Fix this by adding a range check. Note that the array size is defined by a Kconfig symbol (CONFIG_SERIAL_ARC_NR_PORTS), so this can even be triggered using a legitimate DTB.
