Subject: [DRM/I915]: Sync the default modes for LVDS output device
From: Zhao Yakui <yakui.zhao at intel.com>
Sync the default modes for the LVDS output device
This covers:
Add the default modes for the LVDS output device.
The bit of edid->feature.msc indicates whether the display device is not
continous-frequency. And it is used to determine whether the default modes will
be added to the output device.
But for the LVDS output device the edid->feature.msc will always be set.Even
when there is no edid, the corresponding bit in the fake edid will be set.
In such case the default modes will be added to LVDS output device.
If not, the modes obtained by using KMS/UMS will be different.
