** Description changed:

- eDP on haswell graphics puts some stuff in dmsg that is scary to users.
- Worse, these messages are displayed on suspend/resume, and because we
- don't have vt-switchless resume support in ubuntu yet, when the graphics
- don't work it seems like these messages are the culprit.
+ [Impact]
+ 
+  * This confuses end users. They think that this is a relevant message 
instead of an 
+    unimportant accident to the eDP
+ 
+ [Test Case]
+ 
+  * Use an eDP haswell system
+  * See this message in dmesg
+ 
+ [Regression Potential]
+ 
+  * Low. This patch just skips a port check on eDP machines
+  * It has already been tested on eDP machines
+ 
+ [Other Info]
+  
+  * private bug 1097143
  
  
  Dmesg:
