Subject: [PATCH -mm 1/5] PM: Export device_pm_schedule_removal
Date: Fri, 25 Jan 2008 01:30:25 +0100 [thread overview]
Message-ID: <200801250130.26591.rjw@sisk.pl> (raw)
In-Reply-To: <200801250127.21966.rjw@sisk.pl>
From: Rafael J. Wysocki <rjw@sisk.pl>
Move the declaration of device_pm_schedule_removal() to device.h
and make it exported, as it will be used directly by some drivers
for unregistering device objects during suspend/resume cycles in a
safe way.
