From ade3e7fef794781c0798d0cf0f046123842ba550 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 25 Nov 2010 00:08:36 +0100 Subject: ACPI / PM: Add function for device power state initialization Add function acpi_bus_init_power() for getting the initial power state of an ACPI device and reference counting its power resources as appropriate. Make acpi_bus_get_power_flags() use the new function instead of acpi_bus_get_power() that updates device->power.state without reference counting the device's power resources. Signed-off-by: Rafael J.
