iio: accel: sca3000: memory corruption in sca3000_read_first_n_hw_rb()
"num_read" is in byte units but we are write u16s so we end up write twice as much as intended. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Cc: <Stable@vger.kernel.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
