+	This driver provides support for Inspur WMI hotkeys.
+	User used Fn+Q to change the power mode. If desktop applications
+	receive hotkeys(Fn+Q) event, then it get the currently power mode
+	and change the power mode. The desktop applications modify brightness
+	and cpufreq based on power mode.
+
+	To compile this driver as a module, choose M here: the module
+	will be called inspur-wmi.
