+fancontrol: Deal with moving hwmon attributes
+
+Several kernel drivers have already moved their attributes from the
+hardware device to the hwmon class device, and others will follow.
+Teach fancontrol about this possibility and let it adjust the attribute
+paths transparently.
+
+Patch by Jean Delvare <khali@linux-fr.org>.
+See <http://www.lm-sensors.org/changeset/6216>.
