I have started the process of updating lm85.c to the sysfs-interface spec, now that I have a better idea against what to patch for (I am using Greg's git tree as the base). What should a hwmon driver do upon a write to a sysfs entry that is currently unchangeable? This is missing in the sysfs-interface description. The kernel generic sysfs guidelines seems to encourage one to return errors where applicable. I could silently ignore the write (most drivers currently do this) and let the user try to figure it out why writing to something has no effect, or I could return an error, thus failing the write right there. Is there a good reason for not returning errors and instead just silently ignore them (e.g. when trying to write to pwm# when auto_pwm is enabled)? Also, can the mode of a hwmon device's sysfs entry be dynamically changed? -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
