+Subject: ahci: correct enclosure LED state save
+References: bnc#489005
+
+ahci_transmit_led_message saves off the led_state
+with a value that includes the port number OR'd
+in, this incorrect value maybe reported back
+in ahci_led_store.
+
+For instance, if you turn off all the leds for
+port 1 and cat the value back it will report 1
+instead of 0.
+
+# echo 0 > /sys/class/scsi_host/host1/em_message
+# cat /sys/class/scsi_host/host1/em_message
+1
