No indication what flags thse are. Also missing the
actual change to use them in drm_edid.c.

The name of the flag in #define indicates what flag it is, how else do you
want me to add teh indication?

I have done the change in my second patch to use this flag #define 
Use of these flags in other places in drm_edid.c will be follow up patches

SOunds good?
