[libata] ahci: correct enclosure LED state save
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 Signed-off-by: David Milburn <dmilburn@redhat.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
