From d2e5f0c16ad60a7208fd371233e63b73c990ece2 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sun, 23 Dec 2012 00:02:44 +0100 Subject: ACPI / PCI: Rework the setup and cleanup of device wakeup Currently, the ACPI wakeup capability of PCI devices is set up in two different places, partially in acpi_pci_bind() where runtime wakeup is initialized and partially in platform_pci_wakeup_init(), where system wakeup is initialized. The cleanup is only done in acpi_pci_unbind() and it only covers runtime wakeup. Use the new .setup() and .cleanup() callbacks in struct acpi_bus_type to consolidate that code and do the setup and the cleanup each in one place. Signed-off-by: Rafael J.
