From: aknautiy <ankit.k.nauti...@intel.com>
We parse the EDID and add all the modes in the connector's
modelist. This adds CEA modes with aspect ratio information
too, regadless of if user space requested this information or
not.
This patch prunes the modes with aspect-ratio information, from
a connector's modelist, if the user-space has not set the aspect
ratio DRM client cap.
