Subject: hwmon: (lm90) Mark alert as broken for MAX6646/6647/6649
X-Git-Tag: v6.6.17~8307^2~4

hwmon: (lm90) Mark alert as broken for MAX6646/6647/6649

Experiments with MAX6646 and MAX6648 show that the alert function of those
chips is broken, similar to other chips supported by the lm90 driver.
Mark it accordingly.
