The patch looks good to me, I'd like to hear an opinion from Doug (added
to CC).

What is the merge strategy for the series? Do you plan to pick up all
the patches to drm-misc or should we pick up individual patches into
driver trees?

The code here can get use of something like drm_edid_smth_checksum().
'Something', because I could not come up with the word that would make
it clear that it is the declared checksum instead of the actual /
computed one.
