Subject: [PATCH 52/76] ACPI, PCI: Move acpi_dev_run_wake() to ACPI core
Date: Fri, 30 Mar 2012 06:13:55 -0400 [thread overview]
Message-ID: <b24e5098853653554baf6ec975b9e855f3d6e5c0.1333101989.git.len.brown@intel.com> (raw)
In-Reply-To: <1333102459-23750-1-git-send-email-lenb@kernel.org>
In-Reply-To: <09f98a825a821f7a3f1b162f9ed023f37213a63b.1333101989.git.len.brown@intel.com>
From: Lin Ming <ming.m.lin@intel.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.
