Kevin O'Connor	75b89f5261	thermistor: Fallback to using beta if Steinhart-Hart c3 is negative ... If the c3 coefficient is negative it can cause the adc calculations to fail. The c3 shouldn't be negative in practice, so fallback to a simple beta calculation in that case. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>	2018-04-09 12:35:18 -04:00
