Stephen,

Thanks for reporting! I checked powerpc tree.. This is because of commit
8a8d9181 in powerpc tree.. Basically Michael missed one hunk (below hunk in
opal-api.h)

+/* LED Mode */
+#define POWERNV_LED_MODE_LIGHT_PATH    "lightpath"
+#define POWERNV_LED_MODE_GUIDING_LIGHT "guidinglight"
+
+/* LED type */
+#define POWERNV_LED_TYPE_IDENTIFY      "identify"
+#define POWERNV_LED_TYPE_FAULT         "fault"
+#define POWERNV_LED_TYPE_ATTENTION     "attention"
+
+enum OpalSlotLedType {
+       OPAL_SLOT_LED_TYPE_ID = 0,      /* IDENTIFY LED */
+       OPAL_SLOT_LED_TYPE_FAULT = 1,   /* FAULT LED */
+       OPAL_SLOT_LED_TYPE_ATTN = 2,    /* System Attention LED */
+       OPAL_SLOT_LED_TYPE_MAX = 3
+};
+
+enum OpalSlotLedState {
+       OPAL_SLOT_LED_STATE_OFF = 0,    /* LED is OFF */
+       OPAL_SLOT_LED_STATE_ON = 1      /* LED is ON */
+};

@Michael,
  Will you be fixing it or you want me to send separate patch for this one ?
