From 208f2a886a2f6cf329c9fcbf8d29a0dd245cc763 Mon Sep 17 00:00:00 2001 From: David Milburn Date: Fri, 20 Mar 2009 14:14:23 -0500 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 Signed-off-by: David Milburn Signed-off-by: Jeff Garzik Signed-off-by: Tejun Heo --- drivers/ata/ahci.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) Index: linux-2.6.27-SLE11_BRANCH/drivers/ata/ahci.c =================================================================== --- linux-2.6.27-SLE11_BRANCH.orig/drivers/ata/ahci.c +++ linux-2.6.27-SLE11_BRANCH/drivers/ata/ahci.c @@ -1325,7 +1325,7 @@ static ssize_t ahci_transmit_led_message 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
