  16 * Use "vled" as supply id when declaring the regulator consumer:
  17 *
  18 * static struct regulator_consumer_supply pcap_regulator_VVIB_consumers [] = {
  19 *      { .dev_name = "leds-regulator.0", .supply = "vled" },
  20 * };
  21 *
  22 * If you have several regulator driven LEDs, you can append a numerical id to
  23 * .dev_name as done above, and use the same id when declaring the platform
  24 * device:
  25 *
  26 * static struct led_regulator_platform_data a780_vibrator_data = {
  27 *      .name   = "a780::vibrator",
  28 * };

  31 *      .name = "leds-regulator",
  32 *      .id   = 0,
  33 *      .dev  = {
  34 *              .platform_data = &a780_vibrator_data,
