 * Fix missing commit messages in patch emails

These patches offer a fix for a monitor that doesn't report its native
resolution in its EDID.  The idea is setup a new quirk list with width, height,
and refresh rates for each monitor that needs this quirk.  If a monitor is
attached that matches one in this list, the full modeline is calculated with
drm_gtf_mode, the DRM_MODE_TYPE_PREFERRED bit is set, and the new mode is added
to the connector.

The patch also creates a new quirk bit:  EDID_QUIRK_FORCE_MODE.  This bit needs
to be set for the new quirk list discribed above to be checked.

Dylan Semler (2):
  Enhances EDID quirks to allow for specifying and preferring a mode
    not reported in the EDID block.
  Adds EDID force mode quirk for MMT Monitor2Go HD+.
