+ ---help---
+ Support for simple RGB LED devices. Currently supported are:
+ - Riso Kagaku Webmail Notifier
+ - Dream Cheeky Webmail Notifier and Friends Alert
+ - ThingM blink(1)
+ - Delcom Visual Signal Indicator Generation 2
+ - Greynut Luxafor
+
+ To compile this driver as a module, choose M here: the
+ module will be called hid-led.

---help---
- Support for the ThingM blink(1) USB RGB LED. This driver registers a
- Linux LED class instance, plus additional sysfs attributes to control
- RGB colors, fade time and playing. The device is exposed through hidraw
- to access other functions.
+ Support for the ThingM blink(1) USB RGB LED. This driver has been
+ merged into the generic hid led driver. Config symbol HID_THINGM
+ just selects HID_LED and will be removed soon.
