+ * Lenovo Other Method WMI interface driver. This driver uses the fw_attributes
+ * class to expose the various WMI functions provided by the "Other Method" WMI
+ * interface. This enables CPU and GPU power limit as well as various other
+ * attributes for devices that fall under the "Gaming Series" of Lenovo laptop
+ * devices. Each attribute exposed by the "Other Method"" interface has a
+ * corresponding LENOVO_CAPABILITY_DATA_01 struct that allows the driver to
+ * probe details about the attribute such as set/get support, step, min, max,
+ * and default value. Each attibute has multiple pages, one for each of the
+ * fan profiles managed by the GameZone interface, so it must be probed prior
+ * to returning the current_value.
+ *
+ * These attributes typically don't fit anywhere else in the sysfs and are set
+ * in Windows using one of Lenovo's multiple user applications.
