This should be struct max31790_data *data = dev_get_drvdata(dev); struct i2c_client *client = data->client; The above code crashes, since dev is not an i2c client device. Guenter I tested them hundreds of times, but not on the latest kernel version. So I am going to modify them.
It has nothing to do with the kernel version, but with using the devm_ function to register the hwmon device. Guenter _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
