hwmon: (ntc_thermistor) Avoid math overflow The ntc thermistor code was doing math whose temporary result might have overflowed 32-bits. We need some casts in there to make it safe. In one example I found: - pullup_uV: 1800000 - result of iio_read_channel_raw: 3226 - 1800000 * 3226 => 0x15a1cbc80 Signed-off-by: Doug Anderson <dianders@chromium.org> Cc: stable@vger.kernel.org # 3.10+ Signed-off-by: Guenter Roeck <linux@roeck-us.net>
