video: fbdev: pxa3xx-gcu: Fix integer overflow in pxa3xx_gcu_write [upstream commit a09d2d00af53b43c6f11e6ab3cb58443c2cac8a7] In pxa3xx_gcu_write, a count parameter of type size_t is passed to words of type int. Then, copy_from_user() may cause a heap overflow because it is used as the third argument of copy_from_user().
