Input: turbografx - fix potential out of bound access
Patch 17dd3f0f7aa7: "[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.
