Index: linux/drivers/pci/pci-acpi.c =================================================================== --- linux.orig/drivers/pci/pci-acpi.c +++ linux/drivers/pci/pci-acpi.c @@ -266,8 +266,8 @@ static int acpi_pci_set_power_state(stru } if (!error) - dev_printk(KERN_INFO, &dev->dev, - "power state changed by ACPI to D%d\n", state); + dev_info(&dev->dev, "power state changed by ACPI to %s\n", + pci_power_name(state)); return error; }
If a PCI device is put into D3_cold by acpi_bus_set_power(), the message printed by acpi_pci_set_power_state() says that its power state has been changed to D4, which doesn't make sense. In turn, if the device is put into D3_hot, the message simply says "D3" without specifying the variant of the D3 state. Fix this by using the pci_power_name() macro for printing the state name instead of building it from the numeric value corresponding to the given state directly. Signed-off-by: Rafael J.
