/* The Sony icx_key driver reports keys via the /dev/input/event0 device and
 * abuses the standard struct input_event. The input_event.code is split into
 * two parts:
 * - one part giving the code of the key just pressed/released
 * - one part is a bitmap of various keys (such as HOLD)
 * The status of the HOLD can be queried at any time by reading the state of
 * the first LED.
