hwmon: (ntc_thermistor) Add Samsung 1404-001221 NTC
Browse files Browse the repository at this point in the history
This adds the Samsung 1404-001221 NTC thermistor to the
NTC thermistor driver. As far as I can tell it is electrically
compatible with the Murata 47K NTC thermistor.

This thermistor is mounted in a variety of Samsung products.
