Great, this is the approach I prefer too, but...
Now I'm confused. Leaving runtime suspended devices alone is what I was
doing in my subsystem but was told not to. According to
http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg50690.html
"it's generally agreed that _all_ devices should return to full
power during system resume -- even if they were runtime suspended
before the system sleep."
