 * Author: Shuah Khan <shuahkhan@gmail.com>

 *
 *   leds: Rename led_brightness_set() to led_set_brightness()
 *   
 *   Rename leds external interface led_brightness_set() to led_set_brightness().
 *   This is the second phase of the change to reduce confusion between the
 *   leds internal and external interfaces that set brightness. With this change,
 *   now the external interface is led_set_brightness(). The first phase renamed
 *   the internal interface led_set_brightness() to __led_set_brightness().
 *   There are no changes to the interface implementations.
