hwmon: (lm80) fix a missing check of bus read in lm80 probe In lm80_probe(), if lm80_read_value() fails, it returns a negative error number which is stored to data->fan[f_min] and will be further used. We should avoid using the data if the read fails. The fix checks if lm80_read_value() fails, and if so, returns with the error number.
