3.2.72-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Jeffery Miller <jmil...@neverware.com>
commit 09bfda10e6efd7b65bcc29237bee1765ed779657 upstream.
With the radeon driver loaded the HP Compaq dc5750
Small Form Factor machine fails to resume from suspend.
Adding a quirk similar to other devices avoids
the problem and the system resumes properly.
