+	help
+	  This option enables support for monochrome LEDs that are grouped
+	  into multicolor LEDs which is useful in the case where LEDs of
+	  different colors are physically grouped in a single multi-color LED
+	  and driven by a controller that doesn't have multi-color support.
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called leds-group-multicolor.
