While I admit that the term "tachometer speed" is awkward, the max6650 driver is reporting fan speeds in RPM as every other hwmon driver. So I really have no idea what you think is wrong. What did you think "tachometer speed" was, if not the fan speed? Does the max6650 driver not return correct fan speeds for you? -- Jean Delvare SUSE L3 Support -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
