Thank you for your comments, I appreciate :)
I'm sending new mails with the new commit messages.

Good point.
I like the idea of a new patch. I'll start working on it. I can change
this drm_warn here to avoid merge conflicts.

OK, so drm_edid_is_valid() will happily accept NULL and considers
it invalid. You may want to mention that explicitly in the commit
message.

Could you respin this to use the standard [CONNECTOR:%d:%s] form
while at it? Or I guess a patch to mass convert the whole drm_edid.c
might be another option.
Patch looks good.

[Freedreno] [PATCH v2 01/13] gpu/drm: make drm_add_edid_modes() consistent when updating connector->display_info
According to the documentation, drm_add_edid_modes
"... Also fills out the _display_info structure and ELD in @connector
with any information which can be derived from the edid."
drm_add_edid_modes accepts a struct edid *edid parameter which may have a
value or may be null. When it is not null, connector->display_info and
connector->eld are updated according to the edid. When edid=NULL, only
connector->eld is reset. Reset connector->display_info to be consistent
and accurate.
