The scpi hwmon shows the sub-zero temperature in an unsigned integer, which would confuse the users when the machine works in low temperature environment. This shows the sub-zero temperature in an signed value and users can get it properly from sensors. Signed-off-by: Riwen Lu <luriwen@xxxxxxxxxx> Tested-by: Xin Chen <chenxin@xxxxxxxxxx> --- Changes since v1: - Add judgment for sensor->info.class. If it is TEMPERATURE situation, return the sensor value as a signed value, otherwise return it as a unsigned value. --- drivers/hwmon/scpi-hwmon.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/drivers/hwmon/scpi-hwmon.c b/drivers/hwmon/scpi-hwmon.c index 25aac40f2764..45a7e319143d 100644 --- a/drivers/hwmon/scpi-hwmon.c +++ b/drivers/hwmon/scpi-hwmon.c @@ -99,7 +99,10 @@ scpi_show_sensor(struct device *dev, struct device_attribute *attr, char *buf) scpi_scale_reading(&value, sensor); - return sprintf(buf, "%llu\n", value); + if (sensor->info.class == TEMPERATURE) + return sprintf(buf, "%lld\n", value); + else + return sprintf(buf, "%llu\n", value); } static ssize_t -- 2.25.1 No virus found Checked by Hillstone Network AntiVirus
