Dan Carpenter 182d679b22 Input: joydev - prevent potential read overflow in ioctl
The problem here is that "len" might be less than "joydev->nabs" so the
loops which verfy abspam[i] and keypam[] might read beyond the buffer.

Fixes: 999b874f4a ("Input: joydev - validate axis/button maps before clobbering current ones")
