Hello Andrzej,
Thanks for the comment.
If you watch the code flow carefully, this is driven by EDID. So any 
VIC, which is translated/transformed using this array, would be coming 
from the EDID itself.
So I dont think there would be a problem if the mode is defined in the 
EDID section itself, coz we are expecting the TV to know what its 
mentioning in EDID.

This is how a typical flow would look:
- hot-plug
- driver reads modes specified in EDID basic.
- driver parses various CEA extension blocks.
    - For both of the above mentioned steps, driver will probe the 
functions like do_cea_modes which uses edid_cea_modes[] array.
- driver will add the probed modes in EDID, into connector
- driver will pass the connector to userspace
- userspace will pick one of the probed modes for modeset.
- during modeset, we will set VIC part for a CEA mode, in the AVI 
infoframe section.

So in other words, the only source of a VIC (cea_mode) is from TV's own 
EDID.
This means we should never run into an unknown VIC. There can be a 0 VIC 
(for non CEA modes), but not unknown one.
