Hmm. That BUILD_BUG_ON() looks entirely correct, and if that sizeof() doesn't work, then the code doesn't work.

Very strange. It would be interesting to know where that sizeof goes wrong, but it would seem to be something very peculiar to your build environment (either that config, or your compiler).
I just tested with various values, sizeof(*edid) is 144 bytes at that place.
My last good build was with fdaf9a5840ac ("Merge tag 'folio-5.19' of git://git.infradead.org/users/willy/pagecache") And my setup has not changed in anyway since then. Also verified the build failure on my laptop.
