From ed2a4a92f525d3b70c251dcd82e3e3a2d562b338 Mon Sep 17 00:00:00 2001 From: Jeffery Miller Date: Tue, 1 Sep 2015 11:23:02 -0400 Subject: Add radeon suspend/resume quirk for HP Compaq dc5750. 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.
