From b24e5098853653554baf6ec975b9e855f3d6e5c0 Mon Sep 17 00:00:00 2001 From: Lin Ming Date: Tue, 27 Mar 2012 15:43:25 +0800 Subject: [PATCH] ACPI, PCI: Move acpi_dev_run_wake() to ACPI core acpi_dev_run_wake() is a generic function which can be used by other subsystem too. Rename it to acpi_pm_device_run_wake, to be consistent with acpi_pm_device_sleep_wake. Then move it to ACPI core. Acked-by: Rafael J.
