A much better approach, if such notifications are required and make sense,
would be to add it to the hwmon framework. Rewriting drivers just to get
notifications is not a solution.
Besides, did you consider using kobject_uevent() ? The generic gpio driver
uses that mechanism to create udev notifications on alarms.
