As for the "play" sysfs attribute, remove this other non-standard
attribute, so the driver only implements what is required to switch the
LED on and off. Thus, a fade time won't be ideal for some fast-changing
triggers.

When the thingm driver registers an instance of LED class, it creates a
"play" sysfs attribute for this blink(1) specific feature.

Since this feature is not specific to the RGB chip but to the HID device
itself, let's remove this attribute from the LED instance and only
implement what is useful to switch on and off the LED.

This feature is still easily accessible through hidraw.

The ThingM blink(1) is an open source hardware USB RGB LED. It contains
an internal EEPROM, allowing to configure up to 12 light patterns. A
light pattern is a RGB color plus a fade time. This driver registers a
LED class instance with additional sysfs attributes to support basic
functions such as setting RGB colors, fade and playing. Other functions
are still accessible through the hidraw interface.

At this time, the only documentation for the device is the firmware
source code from ThingM, plus a few schematics. They are available at:

This patch is version 3. It updates the name of the source file, the
driver and the led sysfs entry, according to comments from Jiri Kosina
and Simon Wood.
