drm_helper_probe_add_cmdline_mode() prefers using a probed mode matching
a video= argument over calculating our own timings for the user specified
mode using CVT or GTF.
But userspace code which is auto-configuring the mode may want to know that
the user has specified that mode on the kernel commandline so that it can
pick that mode over the mode which is marked as DRM_MODE_TYPE_PREFERRED.
This commit sets the DRM_MODE_TYPE_USERDEF flag on the matching mode, just
as we would do on the user-specified mode when no matching probed mode is
found.

I was skimming around wrt Ville's compact drm_display_mode series and
noticed that this never landed.
The commit brings extra consistency when dealing with user defined
modes, and is:

Ville this may trivially conflict with your work. I suspect you can do
the honours, and apply on top of your series?
That is if you agree with the patch.
Quick glance at the original thread says maybe there were still some
userspace issues unresolved? Not sure.
IIRC the thread ended with Daniel agreeing on the userspace interface,
but asking for some docs and me pointing out that the patch already
updated/clarified the existing docs. After that things got quiet.
So I believe that this is (still) ready to go upstream.
Regards,
Hans
