ray_cs: Fix array bounds warnings.
rx_msg is defined to have a 1 entry array at the end, so gcc warns: drivers/net/wireless/ray_cs.c: In function ‘rx_authenticate’: drivers/net/wireless/ray_cs.c:2436:3: warning: array subscript is above array bounds [-Warray-bounds] drivers/net/wireless/ray_cs.c:2436:3: warning: array subscript is above array bounds [-Warray-bounds] drivers/net/wireless/ray_cs.c:2436:3: warning: array subscript is above array bounds [-Warray-bounds] drivers/net/wireless/ray_cs.c:2436:3: warning: array subscript is above array bounds [-Warray-bounds] drivers/net/wireless/ray_cs.c:2436:3: warning: array subscript is above array bounds [-Warray-bounds] drivers/net/wireless/ray_cs.c:2439:15: warning: array subscript is above array bounds [-Warray-bounds] drivers/net/wireless/ray_cs.c:2452:16: warning: array subscript is above array bounds [-Warray-bounds] drivers/net/wireless/ray_cs.c:2453:18: warning: array subscript is above array bounds [-Warray-bounds] drivers/net/wireless/ray_cs.c:2453:32: warning: array subscript is above array bounds [-Warray-bounds] Use a zero length array and rename to "ray_rx_msg" to make sure we hit all of the necessary cases.
