I'm not entirely sure what you mean here, sorry. Did you mean that we should get some tests to prevent that kind of EDIDs from being accepted by the kernel? If so, I guess it would mean getting a test suite for the EDID parser itself, which is definitely something that should happen at some point but seems a little out of scope to me.

OK. I meant that these are ill-formed EDIDs and the kernel's EDID processing should handle them gracefully. A test could verify this. Not a blocker for this series, of course.

Going through old mails... I'll note that EDIDs in general contain so much garbage that we simply can't reject them if there are issues. They do need to be handled gracefully, of course.
