Subject: [PATCH 2/5][RFT] ACPI / hotplug: Introduce acpi_install_hotplug_notify_handler()
Date: Tue, 28 Jan 2014 23:13:26 +0100 [thread overview]
Message-ID: <695484386.FD09CqapYM@vostro.rjw.lan> (raw)
In-Reply-To: <1508034.JFmpIOzjVZ@vostro.rjw.lan>
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Introduce a helper routine for installing acpi_hotplug_notify_cb()
as an ACPI notify handler for the given ACPI namespace node and make
acpi_scan_init_hotplug() use it.
This is to make subsequent changes easier to follow.
