Dmitry Torokhov c20bc5502d Input: turbografx - fix potential out of bound access 
Patch 17dd3f0f7a: "[PATCH] drivers/input/joystick: convert to dynamic
input_dev allocation" from Sep 15, 2005, leads to the following static
checker warning:

        drivers/input/joystick/turbografx.c:235 tgfx_probe()
        error: buffer overflow 'tgfx_buttons' 5 <= 5

drivers/input/joystick/turbografx.c
   195          for (i = 0; i < n_devs; i++) {
   196                  if (n_buttons[i] < 1)
   197                          continue;
   198
   199                  if (n_buttons[i] > 6) {
                            ^^^^^^^^^^^^^^^^
Possibly off by one.  >= 6.

Let's change the upper value to ARRAY_SIZE(tgfx_buttons) to ensure we do
not reach past the end of the array.
