Subject: PM: Convert wakeup flag accessors to inline functions
To: Greg KH <greg@xxxxxxxxx>
Cc: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>, Alan Stern <stern@xxxxxxxxxxxxxxxxxxx>, Linux-pm mailing list <linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx>, Kernel development list <linux-kernel@xxxxxxxxxxxxxxx>, lenb@xxxxxxxxxx
Message-ID: <200803192239.14091.rjw@xxxxxxx>
Content-Disposition: inline
From: Alan Stern <stern@xxxxxxxxxxxxxxxxxxx>
This patch (as1058) improves the wakeup macros in include/linux/pm.h.
All but the trivial ones are converted to inline routines, which
requires moving them to a separate header file since they depend on
the definition of struct device.
