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 Signed-off-by: Jeff Garzik --- diff --git a/drivers/ata/ahci.c b/drivers/ata/ahci.c index ec2922ad2dc0..788bba2b1e17 100644 --- a/drivers/ata/ahci.c +++ b/drivers/ata/ahci.c @@ -1348,7 +1348,7 @@ static ssize_t ahci_transmit_led_message(struct ata_port *ap, u32 state, writel(message[1], mmio + hpriv->em_loc+4); /* save off new led state for port/slot */ - emp->led_state = message[1]; + emp->led_state = state; /* * tell hardware to transmit the message
