[media] v4l2-ctrls: fix integer overflow in v4l2_g_ext_ctrls() A large cs->count from userspace may overflow the allocation size, leading to memory corruption. v4l2_g_ext_ctrls() can be reached from subdev_do_ioctl() or __video_do_ioctl(). Use kmalloc_array() to avoid the overflow. Signed-off-by: Xi Wang <xi.wang@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
