To: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
Cc: Michael Buesch <mb@xxxxxxxxx>, pm list <linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx>, Alan Stern <stern@xxxxxxxxxxxxxxxxxxx>, Len Brown <lenb@xxxxxxxxxx>, LKML <linux-kernel@xxxxxxxxxxxxxxx>, Pavel Machek <pavel@xxxxxx>, bcm43xx-dev@xxxxxxxxxxxxxxxx, Alessandro Rubini <rubini@xxxxxxxxxxxxxxx>, Richard Purdie <rpurdie@xxxxxxxxx>, Greg KH <greg@xxxxxxxxx>
Message-ID: <200801250130.26591.rjw@xxxxxxx>
Content-Disposition: inline
From: Rafael J. Wysocki <rjw@xxxxxxx>
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.
