From 3d0882c0d10d4b4785aeaf26043e764e3aaca825 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sat, 4 Aug 2012 23:27:32 +0200 Subject: [PATCH] PCI / PM: Fix D3/D3cold/D4 messages printed by acpi_pci_set_power_state() 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.
