From: Jeffery Miller <jmiller@neverware.com>
3.4.112-rc1 review patch. If anyone has any objections, please let me know.
------------------
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.
