+PM support:    Since Linux is used on many portable and desktop systems, your
+               driver is likely to be used on such a system and therefore it
+               should support basic power management by implementing, if
+               necessary, the .suspend and .resume methods used during the
+               system-wide suspend and resume transitions.  You should verify
+               that your driver correctly handles the suspend and resume, but
+               if you are unable to ensure that, please at least define the
+               .suspend method returning the -ENOSYS ("Function not
+               implemented") error.  You should also try to make sure that your
+               driver uses as little power as possible when it's not doing
+               anything.  For the driver testing instructions see
+               Documentation/power/drivers-testing.txt and for a relatively
+               complete overview of the power management issues related to
+               drivers see Documentation/power/devices.txt .

 Control:       In general if there is active maintainance of a driver by
                the author then patches will be redirected to them unless
                they are totally obvious and without need of checking.
