Bug detail Description:
--------------------------------------------
I-G-T testdisplay causes call trace while setting up customized timing. On SNB
platform also has *ERROR* mismatch in clock and Call Trace in dmesg, but here
we restrict this bug to adjusted_mode.flags mismatches. 

[   59.304657] [drm:intel_pipe_config_compare] *ERROR* mismatch in
adjusted_mode.flags (expected 0, found 2)

But for prudential reasons, I will attach the complete dmesg info in the
attachment.

Reproduce Steps:
---------------------------------------------
1.booting up machine
2../testdisplay -f 38.25,800,832,912,1024,600,603,607,624
3.dmesg | grep "ERROR"
