 *  Monitor GPIO for button press
 *  https://www.kernel.org/doc/Documentation/gpio/gpio.txt
 *  drivers/gpio/gpiolib.c
 *
 *  This is a simple kernel module to detect the duration of a button press on a Raspberry Pi 2.
 *  The button press durations are stored in a kfifo. A character device can be read, and the
 *  next available button press will be sent to user space. Only one process can read from
 *  the character device at a time.
