From f6767dcf2a4f6e62960912d0affec1e15a246191 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sat, 11 Dec 2010 23:44:39 +0100 Subject: ACPI / PM: Drop acpi_bus_get_power() There are no more users of acpi_bus_get_power(), so it can be dropped. Moreover, it should be dropped, because it modifies the device->power.state field of an ACPI device without updating the reference counters of the device's power resources, which is wrong.
