Subject: [PATCH 52/76] ACPI, PCI: Move acpi_dev_run_wake() to ACPI core
From: Lin Ming <ming.m.lin@...el.com>
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.
